Lockheed's missile with ramjet engine to offer 620-mile range

Lockheed Martin has unveiled its Increment 4 Precision Strike Missile (PrSM) prototype, featuring a combined-cycle propulsion system that integrates a ramjet engine with a solid rocket motor. This advancement is expected to extend the missile’s range to over 620 miles (1,000 kilometers), nearly doubling the current PrSM range of 320 miles. The missile’s design includes mid-body aerodynamic strakes, a blister fairing, and four aft-mounted control surfaces, enhancing its flight stability and maneuverability. A flight test for this Increment 4 version is planned for 2026 to validate its long-range capability and precision. The new missile aims to improve survivability and lethality by following a critical path to its target, making interception by enemy defenses more difficult. Lockheed emphasizes that the missile will not require booster drops during flight, enhancing operational safety over land and water. The PrSM system is compatible with existing launchers like the MLRS M270 and HIMARS, providing artillery units with extended reach
