The United States Navy has revealed the official schedule for the development of the new Long Range Anti-Submarine Warfare system, designed to replace the current vertical launch missiles and combat modern submarines between the years 2027 and 2031.
The US Navy’s documentation for 2027 details the schedule for the Long Range Anti-Submarine Warfare (LRAW) system. This new anti-submarine weapon aims to extend the range of vertical launch missiles against adversary submarine tactics.
The LRAW program will replace the VLA missile systems, known as the RUM-139 rocket. The VLA uses solid fuel propulsion and a lightweight torpedo, operating on ships equipped with the Aegis system and Mk-41 Vertical Launch System.
The system launches Mk 54 Mod 0 torpedoes to distances greater than 16 kilometers. The new model is expected to maintain the logic of vertical launch assisted by rockets until entering the water, where it begins a helical search trajectory.

Technological Replacement of the Anti-Submarine Weapon
Technical reviews took place between the years 2024 and 2025. The official schedule establishes the start of the program for the first quarter of 2027. The testing and evaluation phases are expected to last exactly five consecutive years.
During the period between 2027 and 2031, modifications will be made to the existing VLA rocket. The work includes the design of containers, construction of prototypes, and necessary engineering qualification for the operation of the planned system prototype.
Schedule and Phases of the LRAW Project
Operational tests will validate the effectiveness of the anti-submarine weapon against modern threats. The development follows the evolution of quieter submarines and unmanned underwater systems. It also considers the use of digital signal processing with artificial intelligence.
The allocated funding reserves $11.42 million for the fiscal year 2027. For the period between 2028 and 2031, the total projected amount is $152.26 million. These resources ensure the continuity of the planned development stages.
Funding and International Cooperation
The documentation mentions AUKUS, suggesting joint development with the United Kingdom and Australia in Pillar II. The project aims to neutralize submarines employing long-range attack tactics. The technology uses digital autopilot to guide the missile.
The LRAW will be launched from cruisers and destroyers integrated with the SQQ-89 combat system. The anti-submarine weapon ensures the protection of surface forces against emerging technologies. The torpedo initiates searches after entering the water in an automated manner.
The schedule mentions joint development to tackle silent submarines and the proliferation of underwater systems. The final testing phases will occur in the fourth quarter of 2031. The system uses thrust vectoring during the programmed flight phases.
