About this opportunity

The Department of the Army Materiel Command Army Contracting Command Aberdeen Proving Ground is seeking prototype development for a Low Altitude Stalking and Striking Ordnance (LASSO) system to address tactical capability gaps for Infantry Brigade Combat Teams during Large Scale Combat Operations. The solicitation targets the development of loitering munition systems capable of providing long-range, precise fire against peer adversary armored vehicles and hardened targets with minimal collateral damage. Vendors must submit a 15-page Solution Brief and 10 PowerPoint slides by July 3, 2025, detailing their technical approach that incorporates Modular Open Systems Architecture (MOSA) principles. Evaluation criteria will focus on technical merit, feasibility, viability, desirability, schedule, and pricing, with the government reserving the right to make multiple awards or no awards at all. The procurement process includes three phases: Solution Brief submission, Oral Presentations, and final Proposal submission.

The solicitation is not set aside for any specific business category and is open to qualified vendors in the Aircraft Manufacturing (NAICS 336411) and Guided Missile Systems (PSC 1425) categories. The place of performance will be Fort Belvoir, Virginia, with potential follow-on production contracts possible after the prototype development phase. While specific award values are not explicitly stated, the pricing sheets indicate potential procurement quantities of 10, 50, and 100 units across various hardware, software, and logistics support line items. The project timeline spans from 2025 to 2029, with multiple milestone reviews and technical documentation requirements throughout the development process. Vendors will need to provide comprehensive documentation including test plans, configuration management plans, training materials, and safety assessments to support the prototype development of this advanced loitering munition system.

AMENDMENT 02 (04 JUNE 2025) - THE SOO WAS UPDATED ALONG WITH MANY ADRLs. PLEASE DOWNLOAD ALL ATTACHMENTS WITH THE TERM (Change) AT THE END FOR THE MOST RECENT VERSIONS.  THERE IS ALSO A LETTER TITLED 'AMENDMENT 2 LETTER OF EXPLANATION (FINAL) FOR YOUR REFERENCE. THANK YOU!

AMENDMENT 01 (22 MAY 2025) - THE CALL FOR SOLUTIONS (.PDF) WAS SIGNIFICANTLY UPDATED - IT IS NOW VERSION 2.1 (V2.1_clean). PLEASE DISREGARD THE INITIAL VERSION AND REFER TO VERSION 2.1 INSTEAD. ALSO UPDATED WAS THE PRICING SHEET AND COMPANY RESPONSE TEMPLATE (FORMERLY CALLED THE VENDOR RESPONSE TEMPLATE) - PLEASE USE THESE VERSIONS INSTEAD AS WELL.

The Infantry Brigade Combat Teams (IBCT) are at risk of failing to achieve tactical overmatch against peer adversary armor vehicles, hardened targets, defilade targets, personnel targets at extended ranges and executing target hand-off with precision fires during Large Scale Combat Operations (LSCO). The Low Altitude Stalking and Strike Ordnance (LASSO) is required due to lack of adequate proportional organic capabilities to apply immediate, point long-range fire with minimal collateral damage in complex terrain in all environments. This Call for Solution requires a technical effort associated with the design, development, fabrication, test, and delivery of prototype loitering munition systems for the LASSO program.
