The U.S. Navy is set to overhaul its torpedo inventory following approval of a new congressional budget that aligns with a military shift toward a "two-war" strategy. This strategy emphasizes the need for sufficient undersea weapons to sustain two major regional conflicts simultaneously.

Manufacturers are focusing on increasing production of MK-48 Advanced Capability (ADCAP) heavyweight torpedoes and MK-54 lightweight torpedoes to meet the minimum base requirements established by the budget.

This move comes amid concerns over depleted missile stockpiles resulting from ongoing conflicts, including the recent 12-day exchange of strikes involving Iran. According to an analysis by the Jewish Institute for National Security of America (JINSA), defending Israel and the Al Udeid Air Base in Qatar from Iranian counterstrikes cost the U.S. and Israel between $1.48 billion and $1.58 billion.

Before June 13, 2026—the day Israel began its offensive in Iran—the U.S. had approximately 632 Terminal High Altitude Area Defense (THAAD) interceptors. JINSA's calculations indicate about 540 interceptors remain in the U.S. arsenal after accounting for deliveries and use.

The Navy's torpedo overhaul reflects broader efforts to rebuild and maintain critical military capabilities amid evolving global security challenges.
