U.S. Approves Proposed $2.3 Billion Sale of P-8A Patrol Aircraft to Singapore

Overview

• The State Department cleared a potential $2.316 billion package featuring up to four Boeing P-8A Poseidon maritime patrol aircraft for Singapore.
• DSCA has notified Congress of the proposed sale, which remains subject to legislative review and subsequent contract negotiations before it can proceed.
• The package includes eight MK 54 Mod 0 lightweight torpedoes and mission systems such as AN/APY-10 radar, AN/AAQ-24(V)N DIRCM, acoustic systems, spares, training and logistics support.
• U.S. officials said the sale would bolster Singapore’s patrol, reconnaissance and anti-submarine capabilities, improve interoperability with U.S. and allied forces, and not change the region’s basic military balance.
• Singapore signaled the acquisition in September 2025 as it moves to replace its ageing Fokker 50 maritime patrol fleet as part of a broader modernization effort.
