This is a pre-solicitation notice for a planned sole-source contract to Lockheed Martin for MLRS fleet upgrades from FY27 through FY31. The work involves recapitalizing or upgrading up to 55 M270 launchers annually and procuring spare parts kits. The government will furnish key components like the launcher cabs and engines, with Red River Army Depot supporting the carrier upgrades. The government states it lacks the full technical data rights and that qualifying another source would cause unreasonable delays. Capability statements may be submitted for consideration, but the solicitation will not be posted publicly.
