GovCon 101: how to buy defense capability, and how to win

Defense capability is bought through several paths. FAR Part 12 buys commercial products and services. Other Transaction Authority (OTA) funds prototypes fast with flexible terms. SBIR Phase III lets an agency sole-source a matured SBIR result. Firm-fixed-price gives cost certainty. The right path depends on maturity, dollar value, and urgency.

Buying defense capability is not one process — it is several, each suited to a different situation. The four that matter most for mature software like DaggerOS are FAR Part 12, Other Transaction Authority (OTA), SBIR Phase III, and firm-fixed-price contracting. Picking the right one is mostly a question of three variables: how mature the capability is, how much it costs, and how urgently it is needed.

FAR Part 12 — commercial products and services

FAR Part 12 is the path for buying things that already exist as commercial products. It uses commercial terms and standard clauses, which keeps the paperwork proportionate and avoids paying to develop what is already built. It fits a capability that is a product, at a defensible maturity, ready to evaluate and field rather than invent.

Other Transaction Authority (OTA) — prototypes, fast

An OTA is an agreement outside the standard Federal Acquisition Regulation, used mainly for prototype projects. Its value is speed and flexibility: it can get a promising capability into a hands-on prototype or evaluation quickly, with terms tailored to the effort. Many programs use an OTA to try before a larger production decision.

SBIR Phase III — fielding a matured small-business result

The Small Business Innovation Research program runs in phases. Phase I proves feasibility, Phase II develops, and Phase III fields the result. Phase III is distinctive: because the competition happened at Phase I/II, an agency can often award Phase III work sole-source, without a further competition, when the work derives from that SBIR or STTR lineage. It is a direct path to put a matured small-business capability into use.

Firm-fixed-price — cost certainty

Firm-fixed-price (FFP) is not a separate door so much as a contract type you can apply on several of these paths. It gives the buyer cost certainty — the price is the price — which program offices value when a capability is mature enough that the risk of open-ended development is low.

How to win, briefly

Winning is mostly about reducing the buyer’s risk:

  • Show maturity honestly. A defensible TRL and a demonstration under realistic, third-party conditions beats a claim. DaggerOS is at TRL 7–8, demonstrated at T-REX 26-2 (May 2026).
  • Keep interfaces open. A modular, open-architecture (MOSA) posture lowers integration risk and avoids lock-in, which makes a program easier to approve. See interoperability in the ISR-fusion domain.
  • Prove the human stays in command. A responsible-autonomy posture aligned to DoDD 3000.09, with an auditable record, is easier to defend in a milestone review.
  • Make the economics legible. Bring the cost trade to the table with your own numbers.

Next steps

The paths above map to real decisions, and the right one depends on your office and your timeline.

When you are ready, request an evaluation.

Frequently asked

What is FAR Part 12?

FAR Part 12 is the Federal Acquisition Regulation path for buying commercial products and services. It uses commercial terms and is well suited to a mature capability that already exists as a product rather than a bespoke development.

What is an Other Transaction Authority (OTA)?

An OTA is an agreement outside the standard FAR, used mainly for prototypes. It moves faster and allows flexible terms, which suits getting a promising capability into a hands-on evaluation quickly.

What is SBIR Phase III?

SBIR Phase III lets an agency award work that derives from an earlier SBIR or STTR effort, often sole-source and without a further competition, because the competition happened at Phase I/II. It is a path to field a matured small-business result.

Which acquisition path is fastest?

For getting hands on a prototype, an OTA is usually the quickest. For a mature commercial product, FAR Part 12 is direct. SBIR Phase III can be fast when a qualifying SBIR lineage already exists. Urgency, maturity, and dollar value decide.
