# Lockheed Tests GD-OTS GMLRS Motor

Lockheed Martin and General Dynamics Ordnance and Tactical Systems completed the first ground test of a new solid rocket motor for the Guided Multiple Launch Rocket System (GMLRS). Qualification is targeted for 2027; if successful, GD-OTS could become a third motor source alongside Northrop Grumman and L3Harris Technologies, expanding potential supply capacity for a key U.S. munitions program. The signals do not specify a contract value, solicitation, or procurement contact.

- A new qualified source could broaden the GMLRS motor supplier base and create opportunities for manufacturers and sub-tier suppliers able to support rocket-motor production.
- Lockheed Martin’s production expansion and related investments may increase demand for manufacturing capacity and components across the munitions supply chain.
- Companies can assess whether their production capabilities align with GMLRS supply-chain needs; the 2027 qualification target is a program milestone, not a stated solicitation deadline.
