About this opportunity
The Defense Information Systems Agency intends to modify the Defense Enclave Services (DES) indefinite delivery/indefinite quantity contract HC104722D0002, awarded to Leidos Corporation on a sole-source basis, to expand scope to include Combatant Command (CCMD) network migrations at no change to the existing ceiling value of $11.504 billion.
The justification rests on only one responsible source under 10 U.S.C. 3204(a)(1) and FAR 6.103-1. DISA determined that Leidos is sole source based on institutional knowledge of DoDNet architecture, automated migration scripts, and proven capability migrating over 40,000 users across approximately 900 sites for Fourth Estate agencies since 2022. Market research involving 24 companies and a Sources Sought Notice confirmed no other vendor possesses the combination of automated endpoint and network migration capabilities, scale, and speed required. The Department of War Chief Information Officer memorandum dated May 22, 2026, directs DISA to execute migrations of all unclassified (NIPR) and classified (SIPR) common use IT services across Fiscal Years 2027 through 2028 for eleven combatant commands. The compressed timeline to complete migrations by end of FY2028 is the driving rationale; the Government estimates approximately $15 million in duplicative costs and schedule delays would result from opening the requirement to competition, jeopardizing zero-trust security and national defense priorities amid advanced artificial intelligence threats. The existing contract runs through July 4, 2032.
Notice text
The DES ID/IQ contract is the enabling contract vehicle for DISA’s consolidation of Common Use Information Technology (IT) and services for the Non-classified Internet Protocol Router Network (NIPRNet) and Secure Internet Protocol Router Network (SIPRNet) domains for the Department of Defense’s Fourth Estate (DoD 4th Estate) agencies. This centralization effort was directed by Deputy Secretary of Defense (DEPSECDEF) memorandum, dated 15 August 2019, entitled “Fourth Estate Network Optimization Execution Guidance”, in which the DEPSECDEF granted DISA the authority to direct the transition of each Defense Agency and Field Activities (DAFA) from disparate, legacy Common Use IT services and assets into a single service provider (SSP) environment. DISA’s Common Use IT network is known as Department of Defense (DoD) Network (DoDNet). Design, planning, and execution of migrations from legacy IT networks to the DoDNet occurs exclusively under the DES ID/IQ contract.
Expanding upon the Fourth Estate Network Optimization initiative, the Department of War (DoW) Chief Information Officer (CIO) issued a memorandum, dated 22 May 2026, (CIO000196-36), titled “Combatant Command (CCMD) Network Optimization Execution Guidance,” attached hereto, which provides, “DISA will execute migrations for all unclassified (NIPR) and classified (SIPR) Common Use Information Technology (IT) across Fiscal Years (FY) 2027 through 2028.”
Based on the short timeframe to complete migrations of CCMDs to DoDNet by the end of FY2028, the DES ID/IQ is the only viable contracting alternative. Upon completion of migration, the preponderance of operations and sustainment activities will be transitioned to the Government.
Awarded contract HC104722D0002 to unknown vendor for unknown amount on 2022-02-28.
