Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General The accompanying condensed consolidated financial statements of Comtech Telecommunications Corp. and its subsidiaries (“Comtech,” “we,” “us,” or “our”) as of and for the three and six months ended January 31, 2017 and for the three and six months ended January 31, 2016 are unaudited. In the opinion of management, the information furnished reflects all material adjustments (which include normal recurring adjustments) necessary for a fair presentation of the results for the unaudited interim periods. Our results of operations for such periods are not necessarily indicative of the results of operations to be expected for the full fiscal year. The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements, and the reported amounts of net sales and expenses during the reported period. Actual results may differ from those estimates. Our condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, filed with the Securities and Exchange Commission (“SEC”), for the fiscal year ended July 31, 2016 and the notes thereto contained in our Annual Report on Form 10-K, and all of our other filings with the SEC. As disclosed in more detail in our Annual Report on Form 10-K for the fiscal year ended July 31, 2016 and "Notes to Condensed Consolidated Financial Statements - Note (15) - Segment Information," beginning with our third quarter of fiscal 2016, we began managing our business in two reportable segments: Commercial Solutions and Government Solutions. Accordingly, certain prior period amounts have been reclassified to conform to current period presentation. We had previously reported three reportable segments: Telecommunications Transmission, RF Microwave Amplifiers and Mobile Data Communications.

The accompanying condensed consolidated financial statements of Comtech Telecommunications Corp. and its subsidiaries (“Comtech,” “we,” “us,” or “our”) as of and for the three and six months ended January 31, 2017 and for the three and six months ended January 31, 2016 are unaudited. In the opinion of management, the information furnished reflects all material adjustments (which include normal recurring adjustments) necessary for a fair presentation of the results for the unaudited interim periods. Our results of operations for such periods are not necessarily indicative of the results of operations to be expected for the full fiscal year.

The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amount of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements, and the reported amounts of net sales and expenses during the reported period. Actual results may differ from those estimates.

Our condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements, filed with the Securities and Exchange Commission (“SEC”), for the fiscal year ended July 31, 2016 and the notes thereto contained in our Annual Report on Form 10-K, and all of our other filings with the SEC.

As disclosed in more detail in our Annual Report on Form 10-K for the fiscal year ended July 31, 2016 and "Notes to Condensed Consolidated Financial Statements - Note (15) - Segment Information," beginning with our third quarter of fiscal 2016, we began managing our business in two reportable segments: Commercial Solutions and Government Solutions.
