The Defense Advanced Research Projects Agency's Tactical Technology Office (TTO) issues an annual Office-wide Broad Agency Announcement — HR001125S0011 for the current cycle — covering proposals for advanced tactical systems and platforms at the intersection of defense engineering and operational readiness. TTO is DARPA's system-integration office, funding large-scale engineering efforts in aerospace systems, unmanned systems, maritime platforms, ground combat systems, and tactical space capabilities. The BAA accepts submissions year-round with a close date of June 22, 2026 for the current cycle.

Award sizes are the largest in DARPA's office portfolio, typically ranging from $5 million to $50 million over 24 to 48 months across multiple program phases, with a pool estimated at $700 million across the office's annual activities. Eligible performers are US-registered for-profit companies, nonprofits, universities, and research organisations operating at TRL 3–7; proposals without defense relevance are outside scope. The standard two-stage process applies — Executive Summary first, Full Proposal by invitation only. Cooperative agreements, Other Transactions, and procurement contracts are all used depending on the nature of the deliverable.

TTO programs are distinguished from other DARPA offices by their emphasis on system-level integration and rapid prototyping toward fielded capability. Proposals that demonstrate a credible pathway from prototype to operational deployment — with quantified performance improvements over current systems — receive the most favourable evaluations. Performers must be registered on SAM.gov. Foreign-component restrictions apply, and classified program extensions are common in later phases.
