Hybrid Acquisition for Proliferated LEO (HALO) Program Solicitation

This is a program solicitation using other transaction authority (OTA) for the Hybrid Acquisition for Proliferated LEO (HALO) effort, the winners of which will be eligible to compete for future prototype orders. HALO is an acquisition approach to solicit and award rapid, affordable mission feasibility demonstrations. This solicitation provides an opportunity for industry to submit proposals for eligibility into an established vendor pool to compete for specific flight demonstration opportunities in the future.

Only vendors in the HALO pool will be able to bid against specific demonstration prototype orders geared toward this effort, with the anticipation of multiple prototype orders being initiated and awarded per year. A key goal of HALO is to put a flexible and fast contracting mechanism in place to compete and award Tranche 2 Demonstration and Experimentation System (T2DES) and other SDA demonstration projects.

HALO will also increase the pool of performers capable of bidding on future SDA programs, including participation in layers of future tranches. HALO will provide opportunities for companies to gain valuable experience working with SDA on demonstration projects. HALO pool members will also be able to work directly with SDA to ensure their security capabilities are sufficient to perform on SDA missions.

HALO is structured as a multiple step competition, with initial selection into the HALO pool limited to non-traditional defense contractors. SDA is expecting multiple initial pool members and intends to review the pool periodically. For more information on the HALO pool requirements for mission success and representative prototype orders, view the full solicitation attached to this announcement. The HALO program solicitation is supplemented by unclassified solicitation documents that make up the Bidder’s Library.

These include compliance and reference documents as well as sample DD 254 templates. To receive the solicitation’s Bidder’s Library via DoD SAFE, please send a request to ussf.pentagon.sda.mbx.sda-ps-24-03@mail.mil with the subject line “SDA HALO Solicitation Content Request”.
