About this opportunity

Written by GovTribe AI · Jan 13, 2026

The Defense Information Systems Agency (DISA) posted a Special Notice announcing industry outreach activities for the Air Defense Communication Services 5 (ADCS5) acquisition, a re-compete of the existing ADCS4 contract set to expire on March 31, 2027. This Special Notice underwent multiple amendments between September 2025 and January 2026, evolving from in-person industry day and site visit events to a virtual format and eventually to a comprehensive market research initiative. The ADCS5 contract is structured as a single-award Indefinite Delivery Indefinite Quantity (IDIQ) agreement with an anticipated annual value of $17 million, organized around a two-year base period plus four two-year option periods. The contract will be awarded through open market procedures, with the Request for Proposal anticipated for release in February 2026 and proposals due in the second quarter of 2026. The primary objective is to solicit industry participation in comprehensive market research activities to inform the upcoming solicitation.

The Special Notice outlines a series of industry engagement activities designed to provide potential contractors with critical information about the ADCS5 program and operational infrastructure. The government conducted a virtual Industry Day on November 18, 2025, limited to four participants per company, with registration due by November 13, 2025, and scheduled multi-site facility tours from December 9-17, 2025, at Tyndall Air Force Base in Florida, the Mobile, Alabama MOD interior site, and Alaska facilities, with registration deadlines of December 1, 2025, and participation capped at two representatives per company on a first-come, first-served basis. Eligible contractors must possess appropriate security clearances (minimum secret level), provide valid government-issued identification, and comply with site-specific security protocols and access requirements. The ADCS5 contract will provide comprehensive operations and maintenance services, discrete project-based task areas, and infrastructure support for air defense communications systems across multiple sites, including the Eastern Air Defense Sector, Western Air Defense Sector, Alaska NORAD Region, and the Air Operations Center, with the government providing existing equipment, software, source codes, and site information to support contractor performance.
