Homeland Defense and Security Technical Area Tasks (HD TATs)

The Department of Defense Washington Headquarters Service awarded this Master IDIQ for homeland defense and security research, development, and analysis on May 1, 2014, with ordering authority that closed on April 30, 2019—the vehicle is no longer active and cannot receive new task orders.

The vehicle supported a wide range of CBRN defense, chemical and biological threat characterization, force protection, medical countermeasures, spectrum management, and critical infrastructure analysis work. Task orders funded research, engineering, testing, and evaluation across domains including joint chemical and biological defense programs, Army rapid equipping and autonomous vehicle initiatives, Navy force health protection, NSA advanced computing research, and terrorism risk assessments for national security agencies.

Battelle Memorial Institute dominates the vehicle, holding 16 of 47 task orders with a combined potential value of $548.5 million—roughly 53 percent of the entire $1.04 billion vehicle. Booz Allen Hamilton accounts for 12 orders valued at $324.6 million. These two primes capture roughly 84 percent of potential value. Mriglobal, Science Applications International Corporation, and Amentum Services together hold the remaining major share, with a long tail of smaller firms splitting the balance.

The Office of the Secretary of Defense placed 28 orders valued at $430.1 million—roughly 41 percent of task-order volume. The Army's materiel commands and the Air Force Materiel Command together account for most of the remaining customer base, with the Marine Corps and other defense agencies contributing a smaller share. This concentration around OSD and Army programs shapes the vehicle's strategic focus.

Ordering momentum declined sharply in the vehicle's final years: 16 orders in 2015 fell to just one in 2019. Nearly all 47 task orders—96 percent—carried no set-aside designation, reflecting an unrestricted competitive procurement. Two orders held small business set-asides. Nearly 79 percent of the combined potential value, or $818.4 million, had been obligated by the vehicle's close date. Delivery orders typically ran on cost-plus-fixed-fee or firm-fixed-price terms, with individual order ceilings ranging from approximately $5 million to over $111 million.

Draw from and build on the homeland defense and security (HD & S) knowledge base of BCOs and in turn add to that knowledge base through the development and delivery of STI resulting from R & D and R & D-related A & AS services.
