The U.S. Army Contracting Command – Aberdeen Proving Ground, Orlando Division is conducting market research on industry interest and capability for a potential open season/rolling admission to the Live Training, Ranges, and Combat Training Centers (LTRaC) Multiple Award Contract (MAC) 2. LTRaC MAC 2 is a small-business set-aside, multiple-award indefinite-delivery, indefinite-quantity vehicle under NAICS 333310. It would support hardware-centric, less-complex continuous technology refreshment, modernization, upgrades, and live-training instrumentation efforts with limited subsystems and no complex interfaces or dependencies. Related efforts include FASIT, DRTS, HITS, JPMRC-IS, CTC-IS, STE-LTS, aviation instrumentation, radio-frequency player units, and U.S. Marine Corps range instrumentation. This is for information and planning only, not a solicitation or commitment to hold an open season or make awards, and interested small businesses should review the attached notice for scope, capability requirements, and submission instructions.
