Accounting Policies [Abstract]
Revenue Recognition	REVENUE RECOGNITION The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, (“ASC 606”). The Company is a leading commercial provider of secure sensor and safety-critical mission processing subsystems. Revenues are derived from the sales of products that are grouped into one of the following three categories: (i) components; (ii) modules and sub-assemblies; and (iii) integrated subsystems. The Company also generates revenues from the performance of services, including systems engineering support, consulting, maintenance and other support, testing and installation. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then determined for the bundled performance obligation. Revenue recognized at a point in time generally relates to contracts that include a combination of components, modules and sub-assemblies, integrated subsystems and related system integration or other services. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 79% and 76% of revenues for the second quarter and six months ended December 27, 2019, respectively. Contracts with distinct performance obligations recognized at a point in time, with or without an allocation of the transaction price, totaled 76% and 78% of revenues for the second quarter and six months ended December 31, 2018, respectively. The Company also engages in long-term contracts for development, production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of complex modules and sub-assemblies or integrated subsystems and related services. Long-term contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material contracts. Total revenue recognized under long-term contracts over time was 21% and 24% of total revenues for the second quarter and six months ended December 27, 2019, respectively. Total revenue recognized under long-term contracts over time was 24% and 22% of total revenues for the second quarter and six months ended and December 31, 2018, respectively. The Company generally does not provide its customers with rights of product return other than those related to assurance warranty provisions that permit repair or replacement of defective goods over a period of 12 to 36 months. The Company accrues for anticipated warranty costs upon product shipment. The Company does not consider activities related to such assurance warranties, if any, to be a separate performance obligation. The Company does offer separately priced extended warranties which generally range from 12 to 36 months that are treated as separate performance obligations. The transaction price allocated to extended warranties is recognized over time in proportion to the costs expected to be incurred in satisfying the obligations under the contract. All revenues are reported net of government assessed taxes (e.g., sales taxes or value-added taxes). Refer to Note L for disaggregation of revenue for the period.
Lessee, Leases	LEASES Effective July 1, 2019, the Company adopted ASC 842, Leases, (“ASC 842”), which requires lessees to recognize a right-of-use (“ROU”) asset and lease liability for most lease arrangements. The Company has adopted ASC 842 using the optional transition method and, as a result, there have been no reclassifications of prior comparable periods due to this adoption. The Company has arrangements involving the lease of facilities, machinery and equipment. Under ASC 842, at inception of the arrangement, the Company determines whether the contract is or contains a lease and whether the lease should be classified as an operating or a financing lease. This determination, among other considerations, involves an assessment of whether the Company can control the underlying asset and have the right to obtain substantially all of the economic benefits or outputs from the asset. The Company recognizes ROU assets and lease liabilities as of the lease commencement date based on the net present value of the future minimum lease payments over the lease term. ASC 842 requires lessees to use the rate implicit in the lease unless it is not readily determinable and then it may use its incremental borrowing rate (“IBR”) to discount the future minimum lease payments. Most of the Company's lease arrangements do not provide an implicit rate; therefore, the Company uses its IBR to discount the future minimum lease payments. The Company determines its IBR with its credit rating and current economic information available as of the commencement date, as well as the identified lease term. During the assessment of the lease term, the Company considers its renewal options and extensions within the arrangements and the Company includes these options when it is reasonably certain to extend the term of the lease. The Company has lease arrangements with both lease and non-lease components. Consideration is allocated to lease and non-lease components based on estimated standalone prices. The Company has elected to exclude non-lease components from the calculation of its ROU assets and lease liabilities. In the Company's adoption of ASC 842, leases with an initial term of 12 months or less will not result in recognition of a ROU asset and a lease liability and will be expensed as incurred over the lease term. Leases of this nature were immaterial to the Company’s consolidated financial statements. The Company has lease arrangements that contain incentives for tenant improvements as well as fixed rent escalation clauses. For contracts with tenant improvement incentives that are determined to be a leasehold improvement that will be owned by the lessee and the Company is reasonably certain to exercise, it records a reduction to the lease liability and amortizes the incentive over the identified term of the lease as a reduction to rent expense. The Company records rental expense on a straight-line basis over the identified lease term on contracts with rent escalation clauses. Finance leases are not material to the Company's consolidated financial statements and the Company is not a lessor in any material lease arrangements. There are no material restrictions, covenants, sale and leaseback transactions, variable lease payments or residual value guarantees in the Company's lease arrangements. Operating leases are included in Operating lease right-of-use assets, Accrued expenses, and Operating lease liabilities in the Company's Consolidated Balance Sheets. The standard had no impact on the Company's Consolidated Statements of Operations and Comprehensive Income or Consolidated Statements of Cash Flows. See Note N to the consolidated financial statements for more information regarding the adoption of this standard.

LEASES

Effective July 1, 2019, the Company adopted ASC 842, Leases, (“ASC 842”), which requires lessees to recognize a right-of-use (“ROU”) asset and lease liability for most lease arrangements.

The Company has arrangements involving the lease of facilities, machinery and equipment.
