DARPA Technical and Analytical Support Services II (TASS II)

The Defense Advanced Research Projects Agency established the DARPA Technical and Analytical Support Services II Master IDIQ on October 16, 2023, with a combined ceiling of $1.25 billion and authority to issue orders through October 15, 2028—roughly two years and two months of ordering authority remaining. The vehicle procures advisory and assistance services, including subject matter expert support to program managers, R&D program oversight, technical and operational research analyses, acquisition support, and program event management across DARPA's technical offices.

Fifteen task orders have been awarded since November 2023, with a combined potential value of $866.7 million and $202.7 million obligated to date (23% of potential). Ordering momentum has declined: six orders in 2023, five in 2024, and four in 2025. The vehicle remains unrestricted, with no set-aside designations across all orders.

Strategic Analysis, Inc. dominates the vehicle by both order count and value, holding five orders representing $314.9 million in combined potential value—roughly 36% of the portfolio. The next four primes—Schafer Government Services, LLC ($195.5 million), Systems Planning And Analysis, Inc. ($137.2 million), ECS Federal, LLC ($105.9 million), and Guidehouse Inc. ($79.5 million)—collectively represent $517.1 million. Two additional primes hold the remaining work. Strategic Analysis and the four named firms capture 96% of combined potential value, indicating significant concentration.

Customer concentration mirrors DARPA's internal structure. The Defense Advanced Research Projects Agency itself funds 14 orders totaling $714.4 million in potential value, leaving one order worth $152.2 million obligated to DOD Washington Headquarters Service. Task orders span DARPA's offices, including the Information Innovation Office, Aerospace Projects Office, Defense Sciences Office, Adaptive Capabilities Office, Contracts Management Office, and Director's Office, with performance periods extending through 2030.

Pricing structures vary: most orders use cost-plus fixed-fee; one order carries labor-hours pricing; one is firm fixed price. Task-order ceilings range from $8,000 for post-award orientation briefings to $195.4 million for Director's Office support. The largest recent awards include a $195.4 million Director's Office order (May 2024) and a $152.2 million Advanced Resilience Directorate order (October 2024).

The scope of TASS is to provide a range of Advisory and Assistance services, required to assist DARPA in accomplishing its mission.
