The Vertical Lift Consortium Other Transaction Agreement (OTA)

The VLC OTA joins industry stakeholders at all levels in collaborating with the Government to speed development of technology and lay the foundation for future vertical lift (FVL) platforms. It allows for the industry's most creative and innovative minds, using VLC as a conduit, to advance innovative FVL prototype concepts to the benefit of all Government end-users in the most cost-efficient manner. The end result maximizes total FVL system effectiveness for the warfighter and minimizes cost to the Government, while protecting proprietary data of VLC Members.

Benefits of the OTA

The OTA Process

Solicitation - The Government will identify those technology concepts it seeks to pursue under the OTA then issue an RPP to the ATI (CAO), acting on behalf of VLC, for the research area(s) to be funded. ATI (CAO) will distribute the calls for proposals to the VLC Members.

Industry Proposal Submission - Each VLC Member will then determine whether to submit any proprietary proposals individually or in conjunction with one or more other VLC Members under the terms and conditions of separate teaming agreements to which VLC is not a party. ATI (CAO) will review the proposals for completeness and conformity with format requirements laid out in the call for proposals.

Technical Evaluation & Source Selection - ATI (CAO) will forward all VLC Member proposals to the Government for its evaluation and competitive selection process. The Government will select the proposals it will fund. The Government will define specific execution details (to include a project SOW, any unique or tailored terms and conditions, and terms for payment) in a Technical Direction Letter that will be issued to the ATI (CAO). ATI (CAO) will enter into Project Agreement(s) for the work selected by the Government for funding with the VLC Members whose proposals have been selected by the Government.

Agreement Award - ATI (CAO), acting on behalf of VLC, will be responsible for the Project Agreement administration of the work funded, while the Government-designated Technical Manager will be responsible for technical management of each project funded, overseeing performance of the Project Agreement Awardees under the project, and reviewing and approving deliverables and Milestone Payments.

Project Annual Review - ATI (CAO) will support an annual review of the performance of all VLC Projects under this OTA. The review will consist of a brief status report of the performance of each project VLC is executing in that given year. The review will also address the aggregate performance under the OTA such as percentage of projects on schedule and within budget, as well as those that have deviated from planned schedules and costs.

Frequently Asked Questions

Are there membership dues?

Member companies pay annual dues to belong to an OT-based collaboration.

How much are membership dues?

Dues vary depending on size and type of company, differing from consortium to consortium. Please see Dues Structure page for current dues amount.

What do membership dues and project award assessments pay for?

Annual dues and project award assessments pay for consortium activities, such as but not limited to: consortium support, meeting costs and support, member application processing, membership management (“good standing” tracking, etc.), executing and managing the financial processes, dues and assessment invoicing and collection, communications efforts, business development and strategic planning efforts, maintaining public and private websites, and supporting any other subcontractors.

Is being a nontraditional defense contractor a requirement to join to the consortium?

No, membership is open to companies and universities which are capable of making a technical contribution to the advancement of technology that the consortium operates.

What is a nontraditional company and how to discern is my company is one?

A nontraditional is a technology provider that does not typically participate in government sponsored research and development. These companies are often small businesses or new companies. They may have innovative technologies, but they lack the contracting resources and experience to navigate the FAR. The OT model is a good way for these companies to access the federal market.

A nontraditional means "an entity that is not currently performing and has not performed, for at least the one-year period preceding the solicitation of sources by the Department of Defense for the procurement or transaction, any contract or subcontract for the Department of Defense that is subject to full coverage under the cost accounting standards prescribed pursuant to section 1502 of title 41 and the regulations implementing such section." 10 USC 2302(9)

How long will it take to get the membership application approved after a company submits?
An application with all necessary documentation and certificates can be processed in as little as 1-2 business days. However, it can take up to several weeks if an applicant needs to obtain a DD2345 or update any expired certificates (, DD2345, DUNS, CAGE). See the Membership Requirements for a listing of all required certificates and instructions for obtaining them. If you have questions regarding these documents, please contact us at
Are OT consortia operating in the technology areas my company is engaged in?
ATI builds and manages customized, national technology consortia across technology sectors as diverse as shipbuilding, ordnance, rotorcraft, electromagnetic spectrum, biotechnology, advanced materials development and advanced manufacturing.
