Significant Accounting Policies and Recent Accounting Standards (Policies) [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Harris Corporation and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “Harris,” “Company,” “we,” “our” and “us” refer to Harris Corporation and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared by Harris, without an audit, in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, such interim financial statements do not include all information and footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for annual financial statements. In the opinion of management, such interim financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of our financial position, results of operations and cash flows for the periods presented therein. The results for the second quarter and first two quarters of fiscal 2016 are not necessarily indicative of the results that may be expected for the full fiscal year or any subsequent period. The balance sheet at July 3, 2015 has been derived from our audited financial statements, but does not include all of the information and footnotes required by U.S. GAAP for annual financial statements. We provide complete, audited financial statements in our Annual Report on Form 10-K, which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management's Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended July 3, 2015 (our “Fiscal 2015 Form 10-K”).
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and these Notes. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying condensed consolidated financial statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In the first quarter of fiscal 2016, we adopted an accounting standard issued by the Financial Accounting Standards Board (“FASB”) that eliminates the requirement for an acquirer in a business combination to retrospectively account for measurement-period adjustments. Instead, the new guidance requires that the cumulative impact of a measurement-period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. This standard is to be applied prospectively. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows. In the second quarter of fiscal 2016, we adopted an accounting standard issued by the FASB that simplifies the presentation of deferred income taxes by requiring entities to classify all deferred tax assets and liabilities as non-current in a classified statement of financial position instead of separating deferred tax assets and liabilities into current and non-current amounts. Consequently, entities may no longer allocate valuation allowances between current and non-current deferred tax assets because those allowances also will be classified as non-current. This standard was applied retrospectively, and as a result, we reclassified certain prior-period amounts in the accompanying Condensed Consolidated Financial Statements (Unaudited) to conform with current-period classifications as follows: In the accompanying Condensed Consolidated Balance Sheet (Unaudited), we reclassified $341 million of current deferred income tax assets from the “Current deferred income taxes” line item in the assets section and $7 million of current deferred income tax liabilities from the “Current deferred income taxes” line item in the liabilities and equity section, which resulted in an increase of $339 million to the “Non-current deferred income taxes” line item in the assets section and a net increase of $5 million to the “Non-current deferred income taxes” line item in the liabilities and equity section. In the accompanying Condensed Consolidated Statement of Cash Flows (Unaudited), we reclassified $7 million from the “Non-current deferred income taxes” line item to the “Income taxes” line item in the operating activities section. Other than those reclassifications, the adoption of this standard did not have any impact on our financial position, results of operations or cash flows.
Accounting Standards Issued But Not Yet Effective	Accounting Standards Issued But Not Yet Effective In May 2014, the FASB issued a comprehensive new revenue recognition standard that supersedes nearly all revenue recognition guidance under U.S. GAAP and International Financial Reporting Standards and supersedes some cost guidance for construction-type and production-type contracts. The guidance in this standard is principles-based, and consequently, entities will be required to use more judgment and make more estimates than under prior guidance, including identifying contract performance obligations, estimating variable consideration to include in the contract price and allocating the transaction price to separate performance obligations. The guidance in this standard is applicable to all contracts with customers, regardless of industry-specific or transaction-specific fact patterns. Additionally, this standard provides guidance for transactions that were not previously addressed comprehensively (e.g., service revenue, contract modifications and licenses of intellectual property) and modifies guidance for multiple-element arrangements. The core principle of this standard is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To help financial statement users better understand the nature, amount, timing and potential uncertainty of the revenue that is recognized, this standard requires significantly more interim and annual disclosures. This standard allows for either “full retrospective” adoption (application to all periods presented) or “modified retrospective” adoption (application to only the most current period presented in the financial statements, as well as certain additional required footnote disclosures). In August 2015, the FASB issued an accounting standards update that defers the effective date of this standard by one year, while permitting entities to elect to adopt one year earlier on the original effective date. As a result, this standard is now effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017, which for us is our fiscal 2019. We are currently evaluating the impact this standard will have on our financial position, results of operations and cash flows.
Stock Options and Other Share-Based Compensation	The fair value as of the grant date of each stock option award was determined using the Black-Scholes-Merton option-pricing model, which used the following assumptions: expected dividend yield of 2.50 percent; expected volatility of 23.01 percent; risk-free interest rates averaging 1.52 percent; and expected term in years of 5.05. The fair value as of the grant date of each restricted stock award was based on the closing price of our common stock on the grant date. The fair value as of the grant date of each performance share unit award was determined based on a fair value from a multifactor Monte Carlo valuation model that simulates our stock price and total shareholder return (“TSR”) relative to other companies in our TSR peer group, less a discount to reflect the delay in payments of cash dividend-equivalents that are made only upon vesting.
Extended Product Warranty	We also sell extended product warranties and recognize revenue from these arrangements over the warranty period. Costs of warranty services under these arrangements are recognized as incurred.
Fair Value Measurements, Recurring Basis	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. • Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances.
Revenue Recognition	Estimates and assumptions, and changes therein, are important in connection with, among others, our segments' revenue recognition policies related to development and production contracts. Revenue and profits related to development and production contracts are recognized using the percentage-of-completion method, generally based on the ratio of costs incurred to estimated total costs at completion (i.e., the “cost-to-cost” method) or the ratio of actual units delivered to estimated total units to be delivered under the contract (i.e., the “units-of-delivery” method) with consideration given for risk of performance and estimated profit. Revenue and profits on cost-reimbursable development and production contracts are recognized as allowable costs are incurred on the contract, and become billable to the customer, in an amount equal to the allowable costs plus the profit on those costs. Development and production contracts are combined when specific aggregation criteria are met. Criteria generally include closely interrelated activities performed for a single customer within the same economic environment. Development and production contracts are generally not segmented. If development and production contracts are segmented, we have determined that they meet specific segmenting criteria. Change orders, claims or other items that may change the scope of a development and production contract are included in contract value only when the value can be reliably estimated and realization is probable. Possible incentives or penalties and award fees applicable to performance on development and production contracts are considered in estimating contract value and profit rates and are recorded when there is sufficient information to assess anticipated contract performance. Incentive provisions that increase earnings based solely on a single significant event are generally not recognized until the event occurs. Under the percentage-of-completion method of accounting, a single estimated total profit margin is used to recognize profit for each development and production contract over its period of performance. Recognition of profit on development and production fixed-price contracts requires estimates of the total cost at completion and the measurement of progress toward completion. The estimated profit or loss on a development and production contract is equal to the difference between the estimated contract value and the estimated total cost at completion. Due to the long-term nature of many of our programs, developing the estimated total cost at completion often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance, the risk and impact of delayed performance, availability and timing of funding from the customer and the recoverability of any claims outside the original development and production contract included in the estimate to complete. At the outset of each contract, we gauge its complexity and perceived risks and establish an estimated total cost at completion in line with these expectations. After establishing the estimated total cost at completion, we follow a standard estimate at completion (“EAC”) process in which management reviews the progress and performance on our ongoing development and production contracts at least quarterly and, in many cases, more frequently. If we successfully retire risks associated with the technical, schedule and cost aspects of a contract, we may lower our estimated total cost at completion commensurate with the retirement of these risks. Conversely, if we are not successful in retiring these risks, we may increase our estimated total cost at completion. Additionally, at the outset of a cost-reimbursable contract (for example, contracts containing award or incentive fees), we establish an estimated total contract value, or revenue, based on our expectation of performance on the contract. As the cost-reimbursable contract progresses, our estimated total contract value may increase or decrease if, for example, we receive higher or lower than expected award fees. When adjustments in estimated total costs at completion or in estimated total contract value are determined, the related impact to operating income is recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Anticipated losses on development and production contracts or programs in progress are charged to operating income when identified.
Evaluation of performance and intersegment sales policy	The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in our Notes to Consolidated Financial Statements in our Fiscal 2015 Form 10-K. We evaluate each segment's performance based on its operating income or loss, which we define as profit or loss from operations before income taxes excluding interest income and expense, royalties and related intellectual property expenses, equity method investment income or loss and gains or losses from securities and other investments. Intersegment sales are generally transferred at cost to the buying segment, and the sourcing segment recognizes a profit that is eliminated. The “Corporate eliminations” line items in the tables below represent the elimination of intersegment sales and their related profits. The “Unallocated corporate expense” line item in the tables below represents the portion of corporate expenses not allocated to our business segments.
Goodwill	In accordance with GAAP, we have reassigned goodwill using a relative fair value approach. Because our accounting for our acquisition of Exelis Inc. and its subsidiaries (collectively, “Exelis”) in the fourth quarter of fiscal 2015 is still preliminary, we assigned the goodwill acquired as a result of the acquisition on a provisional basis. Immediately before and after our goodwill assignments, we completed an assessment of any potential goodwill impairment under our former and new segment reporting structure and determined that no impairment existed. In addition, we test our goodwill for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be an impairment.
Goodwill and Intangible Assets	We test our goodwill and other indefinite-lived intangible assets for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be impairment.

Significant Accounting Policies and Recent Accounting Standards (Policies) [Abstract]

The accompanying condensed consolidated financial statements include the accounts of Harris Corporation and its consolidated subsidiaries. As used in these Notes to Condensed Consolidated Financial Statements (Unaudited) (these “Notes”), the terms “Harris,” “Company,” “we,” “our” and “us” refer to Harris Corporation and its consolidated subsidiaries. Intracompany transactions and accounts have been eliminated in consolidation.

The balance sheet at July 3, 2015 has been derived from our audited financial statements, but does not include all of the information and footnotes required by U.S. GAAP for annual financial statements. We provide complete, audited financial statements in our Annual Report on Form 10-K, which includes information and footnotes required by the rules and regulations of the SEC. The information included in this Quarterly Report on Form 10-Q (this “Report”) should be read in conjunction with the Management's Discussion and Analysis of Financial Condition and Results of Operations and the Consolidated Financial Statements and accompanying Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended July 3, 2015 (our “Fiscal 2015 Form 10-K”).

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and these Notes. These estimates and assumptions are based on experience and other information available prior to issuance of the accompanying condensed consolidated financial statements and these Notes. Materially different results can occur as circumstances change and additional information becomes known.

Instead, the new guidance requires that the cumulative impact of a measurement-period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. This standard is to be applied prospectively. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows.

In the second quarter of fiscal 2016, we adopted an accounting standard issued by the FASB that simplifies the presentation of deferred income taxes by requiring entities to classify all deferred tax assets and liabilities as non-current in a classified statement of financial position instead of separating deferred tax assets and liabilities into current and non-current amounts. Consequently, entities may no longer allocate valuation allowances between current and non-current deferred tax assets because those allowances also will be classified as non-current. This standard was applied retrospectively, and as a result, we reclassified certain prior-period amounts in the accompanying Condensed Consolidated Financial Statements (Unaudited) to conform with current-period classifications as follows:

In the accompanying Condensed Consolidated Balance Sheet (Unaudited), we reclassified $341 million of current deferred income tax assets from the “Current deferred income taxes” line item in the assets section and $7 million of current deferred income tax liabilities from the “Current deferred income taxes” line item in the liabilities and equity section, which resulted in an increase of $339 million to the “Non-current deferred income taxes” line item in the assets section and a net increase of $5 million to the “Non-current deferred income taxes” line item in the liabilities and equity section.
In the accompanying Condensed Consolidated Statement of Cash Flows (Unaudited), we reclassified $7 million from the “Non-current deferred income taxes” line item to the “Income taxes” line item in the operating activities section.

Other than those reclassifications, the adoption of this standard did not have any impact on our financial position, results of operations or cash flows.

Accounting Standards Issued But Not Yet Effective

In May 2014, the FASB issued a comprehensive new revenue recognition standard that supersedes nearly all revenue recognition guidance under U.S. GAAP and International Financial Reporting Standards and supersedes some cost guidance for construction-type and production-type contracts. The guidance in this standard is principles-based, and consequently, entities will be required to use more judgment and make more estimates than under prior guidance, including identifying contract performance obligations, estimating variable consideration to include in the contract price and allocating the transaction price to separate performance obligations.

As a result, this standard is now effective for fiscal years, and interim reporting periods within those years, beginning after December 15, 2017, which for us is our fiscal 2019. We are currently evaluating the impact this standard will have on our financial position, results of operations and cash flows.

Stock Options and Other Share-Based Compensation

The fair value as of the grant date of each stock option award was determined using the Black-Scholes-Merton option-pricing model, which used the following assumptions: expected dividend yield of 2.50 percent; expected volatility of 23.01 percent; risk-free interest rates averaging 1.52 percent; and expected term in years of 5.05.

Extended Product Warranty

We also sell extended product warranties and recognize revenue from these arrangements over the warranty period. Costs of warranty services under these arrangements are recognized as incurred.

Fair Value Measurements, Recurring Basis

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

• Level 1 — Quoted prices in active markets for identical assets or liabilities.

• Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means.

• Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect our own assumptions about the assumptions market participants would use in pricing the asset or liability developed using the best information available in the circumstances.

Revenue Recognition

Estimates and assumptions, and changes therein, are important in connection with, among others, our segments' revenue recognition policies related to development and production contracts. Revenue and profits related to development and production contracts are recognized using the percentage-of-completion method, generally based on the ratio of costs incurred to estimated total costs at completion (i.e., the “cost-to-cost” method) or the ratio of actual units delivered to estimated total units to be delivered under the contract (i.e., the “units-of-delivery” method) with consideration given for risk of performance and estimated profit. Revenue and profits on cost-reimbursable development and production contracts are recognized as allowable costs are incurred on the contract, and become billable to the customer, in an amount equal to the allowable costs plus the profit on those costs.

Development and production contracts are combined when specific aggregation criteria are met. Criteria generally include closely interrelated activities performed for a single customer within the same economic environment. Development and production contracts are generally not segmented. If development and production contracts are segmented, we have determined that they meet specific segmenting criteria. Change orders, claims or other items that may change the scope of a development and production contract are included in contract value only when the value can be reliably estimated and realization is probable. Possible incentives or penalties and award fees applicable to performance on development and production contracts are considered in estimating contract value and profit rates and are recorded when there is sufficient information to assess anticipated contract performance. Incentive provisions that increase earnings based solely on a single significant event are generally not recognized until the event occurs.

Under the percentage-of-completion method of accounting, a single estimated total profit margin is used to recognize profit for each development and production contract over its period of performance. Recognition of profit on development and production fixed-price contracts requires estimates of the total cost at completion and the measurement of progress toward completion. The estimated profit or loss on a development and production contract is equal to the difference between the estimated contract value and the estimated total cost at completion. Due to the long-term nature of many of our programs, developing the estimated total cost at completion often requires judgment. Factors that must be considered in estimating the cost of the work to be completed include the nature and complexity of the work to be performed, subcontractor performance, the risk and impact of delayed performance, availability and timing of funding from the customer and the recoverability of any claims outside the original development and production contract included in the estimate to complete.

After establishing the estimated total cost at completion, we follow a standard estimate at completion (“EAC”) process in which management reviews the progress and performance on our ongoing development and production contracts at least quarterly and, in many cases, more frequently. If we successfully retire risks associated with the technical, schedule and cost aspects of a contract, we may lower our estimated total cost at completion commensurate with the retirement of these risks. Conversely, if we are not successful in retiring these risks, we may increase our estimated total cost at completion. Additionally, at the outset of a cost-reimbursable contract (for example, contracts containing award or incentive fees), we establish an estimated total contract value, or revenue, based on our expectation of performance on the contract. As the cost-reimbursable contract progresses, our estimated total contract value may increase or decrease if, for example, we receive higher or lower than expected award fees. When adjustments in estimated total costs at completion or in estimated total contract value are determined, the related impact to operating income is recognized using the cumulative catch-up method, which recognizes in the current period the cumulative effect of such adjustments for all prior periods. Anticipated losses on development and production contracts or programs in progress are charged to operating income when identified.

Evaluation of performance and intersegment sales policy

The accounting policies of our business segments are the same as those described in Note 1: “Significant Accounting Policies” in our Notes to Consolidated Financial Statements in our Fiscal 2015 Form 10-K. We evaluate each segment's performance based on its operating income or loss, which we define as profit or loss from operations before income taxes excluding interest income and expense, royalties and related intellectual property expenses, equity method investment income or loss and gains or losses from securities and other investments. Intersegment sales are generally transferred at cost to the buying segment, and the sourcing segment recognizes a profit that is eliminated. The “Corporate eliminations” line items in the tables below represent the elimination of intersegment sales and their related profits. The “Unallocated corporate expense” line item in the tables below represents the portion of corporate expenses not allocated to our business segments.

Goodwill

In accordance with GAAP, we have reassigned goodwill using a relative fair value approach. Because our accounting for our acquisition of Exelis Inc. and its subsidiaries (collectively, “Exelis”) in the fourth quarter of fiscal 2015 is still preliminary, we assigned the goodwill acquired as a result of the acquisition on a provisional basis. Immediately before and after our goodwill assignments, we completed an assessment of any potential goodwill impairment under our former and new segment reporting structure and determined that no impairment existed.

In addition, we test our goodwill for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be an impairment.

Goodwill and Intangible Assets

We test our goodwill and other indefinite-lived intangible assets for impairment annually, or under certain circumstances, more frequently, such as when events or circumstances indicate there may be impairment.
