Other Transaction Authority (OTA): The Fastest Path to Defense Innovation Contracts

The Other Transaction Authority (OTA) is the federal government's escape hatch from the Federal Acquisition Regulation — allowing the Department of Defense to execute prototype projects and research agreements with commercial companies, startups, and non-traditional contractors without the complexity of FAR-based contracting.

OTAs have become one of the fastest-growing acquisition tools in defense, with DoD obligating billions annually through OTA agreements that can be executed in weeks rather than months.

What Is Other Transaction Authority?

OTA refers to a class of agreements authorized by statute that are specifically not contracts, grants, or cooperative agreements. Instead, they are "other transactions" — a distinct legal instrument with their own rules set by Congress rather than the FAR.

The primary OTA statutes for DoD:

• 10 U.S.C. § 4021 — Research OTAs (for basic/applied research)
• 10 U.S.C. § 4022 — Prototype OTAs (the most commonly used)
• 10 U.S.C. § 2371b — Follow-on production (OTA-to-production pathway)

Key features of OTAs:

• FAR does not apply (no standard clauses, no complicated terms and conditions)
• No requirement for certified cost or pricing data (TINA does not apply)
• Intellectual property terms are negotiated, not imposed by statute
• CAS (Cost Accounting Standards) does not apply
• More flexible performance metrics and milestones

Who Can Use OTAs?

OTAs are available to:

• DoD — the primary OTA user; most Army, Navy, Air Force, DARPA, DHA, and combatant command programs
• DHS — limited OTA authority for research
• DOT — limited authority for some R&D programs
• NASA — has its own "Space Act Agreement" authority, distinct from but similar to OTA

Most OTA activity is concentrated in DoD and administered through:

• DARPA — advanced research OTAs for breakthrough technologies
• Army Futures Command (AFC) / Army Contracting Command
• Naval Air Systems Command (NAVAIR) and NAVSEA
• Air Force Research Laboratory (AFRL) and AFWERX
• Defense Innovation Unit (DIU) — specializes in rapid commercial OTAs
• National Security Innovation Network (NSIN)
• Service-specific innovation hubs (Army xTechSearch, Air Force SBIR Enhancement, etc.)

Prototype OTAs: The Most Common OTA Type

Prototype OTAs under 10 U.S.C. § 4022 allow DoD to award agreements for prototype projects. The concept of "prototype" is broadly interpreted — it doesn't have to be a physical product. It can include:

• A software prototype (minimum viable product, proof of concept)
• A pilot project (deploying a new capability in a limited operational context)
• A new business process or training approach
• Integration of commercial technology into military systems

The 33% non-traditional requirement: To use Prototype OTA, at least one of the following must be true:

• At least one "non-traditional defense contractor" is performing a significant portion of the project
• At least one "traditional defense contractor" is participating to a significant extent
• The government determines the use of OTA is necessary to meet national security objectives

Non-traditional defense contractor: A company that is NOT currently performing and has not performed, for at least one year prior to solicitation, any DoD contract or subcontract subject to full CAS coverage. This definition includes most startups and commercial technology companies.

The Follow-On Production Pathway

One of the most powerful features of the Prototype OTA authority is the follow-on production pathway at 10 U.S.C. § 4022(f):

If a prototype project is successfully completed, DoD can award a follow-on production contract or OTA to the prototype performer without competition — as long as the original OTA was competed (or included adequate competition among alternatives).

This creates a compelling incentive for commercial companies: win a prototype OTA, demonstrate success, and transition to a sole-source production contract — all without a full FAR-based competition.

OTA Consortia

Many OTA programs are administered through OTA Consortia — non-profit organizations that manage OTA relationship between DoD and industry, allowing rapid access to qualified member companies.

Major OTA consortia:

• NSTXL (National Security Technology Accelerator): Multiple agreement vehicles across DoD programs
• Consortium for Command, Control and Communications in Cyberspace (C5): C4ISR and cyber programs
• AFWERX: Air Force innovation arm, manages consortium OTAs
• DIU Agreements: DIU uses OTAs outside the traditional consortium model for speed

How consortia work:

1. A company applies and is accepted as a consortium member (typically a one-time or annual membership)
2. DoD posts "Calls for White Papers" or solicitations through the consortium
3. Members respond to relevant calls
4. Winning proposals lead to individual OTA "Project Agreements" between DoD and the company
5. The consortium manages contract vehicle administration

Consortium benefits for small companies: Membership is typically low-cost and provides access to multiple DoD programs. One application process gives you access to numerous OTA solicitations.

How to Access OTA Opportunities

Defense Innovation Unit (DIU)

DIU (diu.mil) is DoD's commercial technology adoption office. DIU uses "Commercial Solutions Openings" (CSOs) as their primary OTA solicitation mechanism:

• Problem statements are publicly posted
• Industry responds with white papers or solution briefs
• DIU evaluates and selects companies for prototype agreements
• Evaluation is qualitative (not lowest-price technically acceptable) — focuses on commercial maturity and technical approach

DIU is particularly accessible to startups and commercial technology companies. They actively seek non-traditional contractors with commercially mature products that can be adapted to defense needs.

AFWERX

AFWERX is the Air Force's innovation hub. AFWERX manages:

• SBIR/STTR programs (including a special SBIR Open Topics pathway)
• Open Calls for commercial technology
• Accelerator programs for companies at early commercial stages

AFWERX regularly posts calls through the AFWERX Challenge platform.

DARPA

DARPA is the gold standard for high-risk, high-reward defense research OTAs. DARPA:

• Posts solicitations through Broad Agency Announcements (BAAs) and DARPA Open Catalog
• Evaluates on technical novelty and approach quality
• Funding is typically $1M–$10M+ for high-impact research

DARPA is difficult to access — proposals must be genuinely novel. But awards have long tails: DARPA-funded research has produced GPS, the internet, Siri, and stealth aircraft.

SAM.gov OTA Postings

Many DoD OTA solicitations are posted on SAM.gov with contract type codes for "Other Transaction" agreements. Filter SAM.gov by "Other Transactions" award type to find open OTA solicitations.

IP Rights in OTA Agreements

Unlike FAR-based contracts, IP rights in OTAs are negotiated rather than prescribed. This creates both opportunity and risk:

Opportunity: Companies may be able to retain broader IP rights than FAR Part 27 would allow — particularly for inventions developed with mixed government/commercial funding.

Risk: Government negotiators may push for extensive IP rights that undermine commercial value. Understanding what IP rights you need to preserve commercial viability is essential before entering OTA negotiations.

Common OTA IP terms include:

• Government-purpose rights (most common): government can use the technology for government purposes but you retain commercial rights
• Limited rights: proprietary data and software protected
• Unlimited rights: government can use freely (avoid this if possible for commercial technology)

Key Takeaways

• OTAs are statutory agreements that bypass the FAR — no standard clauses, no TINA, no CAS — enabling faster, more flexible prototype agreements for DoD.
• Prototype OTAs (10 U.S.C. § 4022) are the most common type — "prototype" is broadly interpreted to include software pilots, business process pilots, and technology integrations.
• Non-traditional defense contractors (companies not subject to full CAS for at least one year) are specifically targeted by OTA policy — startups and commercial tech companies qualify.
• Follow-on production pathway allows sole-source production awards after successful prototype completion — the most powerful OTA feature for commercial companies.
• OTA consortia (NSTXL, C5, AFWERX) provide consortium member companies with access to multiple DoD OTA solicitations through a single membership application.
• DIU Commercial Solutions Openings are the most accessible OTA pathway for non-traditional contractors — qualitative evaluation, problem-statement format, and commercial-technology focus.
