The US State Department has authorised a potential Foreign Military Sale (FMS) to Singapore, involving P-8A Maritime Patrol and Reconnaissance Aircraft, MK 54 lightweight torpedoes, and associated equipment.
The potential FMS comes after Singapore’s defence ministry stated in September 2025 that it plans to acquire four Boeing P-8A Poseidon maritime patrol aircraft to replace its ageing Fokker-50 fleet. The estimated value of the transaction is $2.32bn.

By GlobalDataThe Defense Security Cooperation Agency (DSCA) delivered the required certification notifying Congress, with Boeing acting as the principal contractor.
Most of the MK 54 lightweight torpedo components will be sourced directly from US Navy inventory.
Various other companies contracted with the US Navy are expected to provide additional components and engineering services throughout the sale implementation.
According to DSCA, up to 14 representatives from the US Government and involved contractors will have to travel to Singapore for up to two years to assist with aircraft fielding and maintenance, mission system integration, training delivery, logistics management and technical support.
The proposed sale is expected to advance foreign policy and security objectives by strengthening Singapore’s maritime capabilities and enhancing cooperation between Singaporean and US forces.
The agreement is also designed to improve Singapore’s defence abilities against current and future security challenges.
