Accounting Policies [Abstract]
Segment Reporting	The Company has five customer facing business groups supported by the enterprise organizations, including the Innovation Factory. The Company's five business groups, which are also its operating segments, are aggregated into two reportable segments for financial reporting purposes given the similarity in economic and qualitative characteristics, and based on the nature of the customers they serve. The Company’s two reportable segments are the Defense and Intelligence segment and the Civilian segment. The Defense and Intelligence segment provides a diverse portfolio of national security solutions to the Department of Defense ("DoD") and Intelligence Community of the United States Government. The Civilian segment provides solutions to the civilian markets, encompassing federal, state, and local governments, in order to deliver services for citizen well-being, border security, and protecting lives. This includes integrating solutions into a spectrum of public service missions that impact travel, trade, health and the economy. The offerings of both reportable segments entail the integration of emerging technologies into mission critical operations that modernize and enable national imperatives, including IT modernization, digital engineering, artificial intelligence ("AI"), mission systems support and advisory, training and simulation, and ground vehicles support. These services include end-to-end solutions spanning the design, development, integration, deployment, management and operations, sustainment and security of the customers’ entire IT infrastructure. The Company's Innovation Factory supports the operating segments by developing enterprise-class solutions which are delivered to the Company's customers as stand-alone solutions or integrated with and aligned to the Company's product offerings through the operations of the business to meet complex customer needs and accelerate digital transformation. The Innovation Factory includes designated teams focused on AI, application development, network services, platforms and cloud, engineering, and cybersecurity. It uses a highly automated, cloud-hosted tool set to rapidly build, test and deploy solutions and works with customers to enhance solutions going forward. Costs associated with corporate functions that are not allocable to the reportable segments are presented as Corporate activities.
Basis of Presentation	References to “financial statements” refer to the condensed consolidated financial statements of the Company, which include the statements of income and comprehensive income, balance sheets, statements of equity and statements of cash flows. These financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP").
Consolidation	All intercompany transactions and account balances within the Company have been eliminated.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. Significant estimates inherent in the preparation of the financial statements may include, but are not limited to, estimated profitability of long-term contracts, income taxes, fair value measurements, fair value of goodwill and other intangible assets, pension and defined benefit plan obligations, and contingencies. Estimates have been prepared by management on the basis of the most current and best available information at the time of estimation and actual results could differ from those estimates.
Reporting Periods	Reporting Periods The Company utilizes a 52/53 week fiscal year ending on the Friday closest to January 31, with fiscal quarters typically consisting of 13 weeks. Fiscal 2026 began on February 1, 2025 and ends on January 30, 2026, while fiscal 2025 began on February 3, 2024 and ended on January 31, 2025.
Operating Cycle	Operating Cycle The Company’s operating cycle may be greater than one year and is measured by the average time intervening between the inception and the completion of contracts.
Derivative Instruments Designated as Cash Flow Hedges	Derivative Instruments Designated as Cash Flow Hedges Derivative instruments are recorded on the condensed consolidated balance sheets at fair value. Unrealized gains and losses on derivatives designated as cash flow hedges are reported in other comprehensive income (loss) and reclassified to earnings in a manner that matches the timing of the earnings impact of the hedged transactions. Settlement amounts related to derivatives designated as cash flow hedges are presented within operating activities on the condensed consolidated statement of cash flows. The Company’s fixed interest rate swaps are considered over-the-counter derivatives, and their fair value is calculated using a standard pricing model for interest rate swaps with contractual terms for maturities, amortization and interest rates. Level 2, or market observable inputs (such as yield and credit curves), are used within the standard pricing models in order to determine fair value. The fair value is an estimate of the amount that the Company would pay or receive as of a measurement date if the agreements were transferred to a third party. See Note 7—Derivative Instruments Designated as Cash Flow Hedges for further discussion on the Company’s derivative instruments designated as cash flow hedges.
Marketable Securities	Marketable Securities Investments in marketable securities consist of equity securities, which are recorded at fair value using observable inputs such as quoted prices in active markets (Level 1). As of August 1, 2025 and January 31, 2025, the fair value of the Company's investments totaled $36 million and are included in "Other assets" on the condensed consolidated balance sheets. The Company's investments are primarily held in a custodial account, which includes investments to fund its deferred compensation plan liabilities.
Accounting Standards Updates	Accounting Standards Updates Accounting Standards Updates Recently Adopted In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. Amongst other amendments, the standard requires annual and interim disclosures of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM"), and interim disclosures about a reportable segment’s profit or loss and assets that are currently required annually. This standard does not change how an entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The standard was effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted the annual disclosure requirements in fiscal 2025 and adopted the interim disclosure requirements in fiscal 2026. See Note 10—Business Segments Information for additional information. Accounting Standards Updates Recently Issued But Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard includes amendments that enhance annual income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments can be applied on a prospective or retrospective basis. The Company plans to adopt this standard prospectively in fiscal 2026 and does not expect it to have a material impact on its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard includes new disclosure requirements relating to specified categories of expenses (purchases of inventory, employee compensation, depreciation, and amortization) that are included in certain expense captions presented on the face of the income statement. Early adoption is permitted. The amendments can be applied on a prospective or retrospective basis. In January 2025, the FASB clarified the effective date of the standard by issuing ASU No. 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The standard is effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of adoption of this standard on its financial statement disclosures.
Earnings Per Share	Earnings Per Share ("EPS") Basic EPS is computed by dividing net income by the basic weighted-average number of shares outstanding. Diluted EPS is computed similarly to basic EPS, except the weighted-average number of shares outstanding is increased to include the dilutive effect of outstanding stock-based awards. The dilutive effect of outstanding stock-based awards is computed using the treasury stock method.
Change in Estimates and Disaggregation of Revenues	Changes in Estimates on Contracts Changes in estimates of revenues, cost of revenues or profits related to performance obligations satisfied over time are recognized in operating income in the period in which such changes are made for the inception-to-date effect of the changes. Changes in these estimates can occur routinely over the performance period for a variety of reasons, which include: changes in scope; changes in cost estimates due to unanticipated cost growth or reassessments of risks impacting costs; changes in the estimated transaction price, such as variable amounts for incentive or award fees; and performance being better or worse than previously estimated. A significant portion of the Company's contracts recognize revenue on performance obligations using a cost input measure (cost-to-cost), which requires estimates of total costs at completion. In cases when total expected costs exceed total estimated revenues for a performance obligation, the Company recognizes the total estimated loss in the quarter identified. Total estimated losses are inclusive of any unexercised options that are probable of award, only if they increase the amount of the loss. Disaggregation of Revenues The Company's revenues are generated primarily from long-term contracts with the U.S. government including subcontracts with other contractors engaged in work for the U.S. government. The Company disaggregates revenues by customer, contract type and prime versus subcontractor to the federal government for each of its reportable segments.

Change in Estimates and Disaggregation of Revenues

Changes in Estimates on Contracts

Changes in estimates of revenues, cost of revenues or profits related to performance obligations satisfied over time are recognized in operating income in the period in which such changes are made for the inception-to-date effect of the changes. Changes in these estimates can occur routinely over the performance period for a variety of reasons, which include: changes in scope; changes in cost estimates due to unanticipated cost growth or reassessments of risks impacting costs; changes in the estimated transaction price, such as variable amounts for incentive or award fees; and performance being better or worse than previously estimated.

In cases when total expected costs exceed total estimated revenues for a performance obligation, the Company recognizes the total estimated loss in the quarter identified. Total estimated losses are inclusive of any unexercised options that are probable of award, only if they increase the amount of the loss.

Disaggregation of Revenues

The Company's revenues are generated primarily from long-term contracts with the U.S. government including subcontracts with other contractors engaged in work for the U.S. government. The Company disaggregates revenues by customer, contract type and prime versus subcontractor to the federal government for each of its reportable segments.
