Project detail

What project A58 buys

Mobile Brigade Combat Teams (MBCTs) lack adequate organic capabilities at echelon to apply immediate, point, long range, and direct fire effects to destroy tanks, light armored vehicles, hardened targets, targets in defilade, and personnel targets, while producing minimal collateral damage in complex terrain in all environmental conditions. Development will focus on the Fire Control Stations (FCS), All-Up Round (AUR), and System Architecture. System Architecture will include integrating with Soldier Borne Mission command (SBMC), Next Generation Command and Control (NGC2) and complete Universal Vehicle Control (UVC) compliance and integration. Develop technology for incorporation into the CDD update, for the enduring program, and conduct tech enhancements from current global conflicts. In addition, LASSO is supporting Transformation in Contact (TiC) in support of Indo-Pacific efforts to expand prepositioned stocks and increase deployments and exercises to support strategic presence in the region. FY 2027 RDT&E funding will be used to conduct evaluations of technologies and capabilities in the loitering munitions capability space, hardware and system architecture engineering and integration activities, and testing and evaluation activities. LASSO is awarding up to four hardware contracts to modernize the industrial base and generate the domestic ammunition stockpiles. The total cost of the Low Altitude Stalking and Strike Ordinance (LASSO) Middle Tier of Acquisition (MTA) effort is $209.4 million RDT&E from FY25 to FY29. This includes FY25 Base funding of $15.767 million and mandatory funding of $12.587 million on 0604827A Project LS2.

FY2027 planned work Funding will continue the evaluation of critical capabilities, assess vendor and market maturity, and conduct safety and qualification testing.

FY2026 to FY2027 change Decrease in FY 2027 is attributed to the program shift in focus from prototype procurement to test and evaluation.

FY2026 plans — current year Funding will continue the evaluation of critical capabilities, assess vendor and market maturity, and conduct safety and qualification testing.
