Basic Research BAA Solicitation:HDTRA1-11-21-BRCWMD-BAA

Basic (6.1) research; In effect March 2011-September 2021

Historically, one annual opportunity solicited by an Amendment to the BAA posted to Grants.gov in early December.

However, with the transition of the DTRA Basic Research Program to the Chief Scientist and Innovations Department, a consolidation of solicitations has taken place to streamline processes and to present a single opportunity to the university-centric research community.

This transition began with the December 1, 2016 publication of FY2018 Basic Research Topics within the Fundamental Research BAA, HDTRA1-14-24-FRCWMD-BAA (see next slide).

The Basic Research BAA Solicitation is valid for use through September 2021 should the Chief Scientist and Innovations Department choose to use it, but the current intent is not to use this BAA for future topics.

28


Fundamental Research BAA Solicitation: HDTRA1-14-24-FRCWMD-BAA

In effect March 2015-September 2024; posted at Grants.gov

General Thrust Areas continuously OPEN for submissions; TRL1 - early 4• Basic and exploratory Applied Research (6.1 & 6.2)• Required: ~250-word abstract to applicable Thrust Area E-mail address

detailed in BAA; based on interest a white paper may/may not be invited • Majority of awards will be grants; other award types are permissible

Annual Basic Research Topics generally posted in late fall • Responses to these topics must address only basic research (6.1)• These topics do NOT require abstract pre-coordination • Deadline for white paper submission will be provided with topic descriptions• The predominance of awards for basic research topics will be grants

All applications MUST be submitted to Grants.gov using the application packages posted with the opportunity.

Questions? Email: [email protected] Government Call: HDTRA1-16-24-FRCWMD-CALL

29


Science and Technology New Initiatives BAA Solicitation: HDTRA1-17-S-0002-BAA

In effect November 2016-October 2021; posted at Fbo.gov

Efforts that advance technical state-of-the-art or increase knowledge and understanding of overarching challenges for countering WMD; TRL2 - 6

BAA will be conducted via a single phase: formal proposal submissionOfferors may choose to pre-coordinate a white paper/quad chart as detailed in the BAA. Pre-coordination, while strongly encouraged, is not mandatory.

Six R&D Technology Areas (TAs): Chemical/Biological; Counter WMD; Radiation/Nuclear; Reach-back and Decision Support; Treaty Verification/Compliance; and Technology Forecasting

BAA continuously OPEN for submissions to the R&D TAsOn a limited basis, Addendums to the BAA may be published that detail more specific or urgent topics. Topics posted in Addendums are likely to have formal proposal deadlines and be available for a limited time.
