Navy Seeks Glide-Torpedo Contractors; 18-Month Prototype Timeline for Anti-Submarine Weapon

The U.S. Navy issued a Request for Information on August 25 for the Silent Anvil Air-Launched Torpedo (SAA-LT), seeking contractors to develop either a new glide torpedo or a glide kit for existing Mark 54 torpedoes, with a prototype due within 18 months of award. The weapon must weigh no more than 268 pounds, fit standard bomb racks, and launch from manned or unmanned aircraft at altitudes up to 60,000 feet, with responses due by September 29.

The glide-kit option mirrors the high-altitude anti-submarine warfare (HAASW) system already operational on P-8s, but the 60,000-foot altitude ceiling and unmanned-platform language signal a shift toward Triton as the primary ASW platform for denied-access zones. If a contractor achieves 10+ nautical miles of glide range from that altitude, the Navy trades manned sortie rates for persistence—a Triton loitering for 24 hours at 60,000 feet launches far fewer weapons but covers vastly more ocean than a P-8 cycling through 4-hour patrols.

WHY IT MATTERS

NAVSEA is forcing a design competition before committing production dollars, which means the Navy is serious about fielding an ASW standoff weapon before the PLA's submarine expansion forces a capability gap.

The 18-month prototype timeline and 60,000-foot altitude requirement point to MQ-4C Triton integration—extending ASW reach beyond P-8 Poseidon coverage to unmanned platforms operating from forward bases where crewed aircraft cannot sustain. If either glide option clears the September 2027 demonstration gate, the Navy will have a cheap, internal-carriage ASW round that multiplies platform availability without new airframes. Watch the September 29 response deadline and whether Raytheon, Northrop, or a smaller integrator wins the prototype phase—the winner locks integration work on the Navy's entire unmanned ASW architecture through the 2030s.

WHAT THIS DOESN’T TELL US

Does the RFI specify maximum range for the glide phase, or is the Navy deliberately leaving that open to see what contractors propose before deciding the standoff distance requirement?
