Navies reduce the danger of torpedo testing by checking systems ashore, using non-explosive exercise weapons when suitable, running sea trials in managed test ranges, and recovering weapons for inspection and data analysis. These measures reduce exposure; they do not make testing risk-free or remove the need for realistic trials. The procedures described below are documented examples from the U.S. Navy and Royal Navy, not a universal rule for every navy.
Why test a torpedo without an explosive warhead?
An exercise torpedo can test a weapon’s operation without carrying an explosive warhead. It can follow a programmed route and provide a way to assess hardware, software, and performance. Depending on the test, it may run against a target or follow a programmed geometry without one.

The U.S. Navy’s September 2024 draft Atlantic Fleet Training and Testing environmental review describes non-explosive trials involving heavyweight, lightweight, and experimental torpedoes. The stated purpose includes evaluating performance and hardware or software upgrades. Not every test includes acoustic activity. For the activity described in that review, the Navy identifies no in-water explosives. The review’s activity description and parameters concern proposed U.S. Atlantic Fleet activity, not all torpedo tests.

Some evaluations can take place on land before a weapon goes to sea. At the Naval Undersea Warfare Center Division, Keyport, Washington, the Weapons System Test Facility was built for land-based evaluation of undersea weapons capabilities, including torpedoes and sensors. Its pressure chamber can test torpedoes, sensors, and unmanned underwater vehicles in operational environments.

The chamber supports particular investigations; it does not reproduce every aspect of a sea trial. A 2025 Department of Defense feature describes measurements of a sound source’s directivity, pulse length, loudness, and frequency, illustrating the kind of system questions the facility can address. The Keyport facility report documents this one site, not a claim that all torpedo behavior can be tested indoors.
The U.S. Navy’s environmental FAQ says most systems undergo land-based testing before entering the water, and many are also tested in smaller freshwater areas or tanks. That is general Navy guidance rather than a torpedo-specific protocol. The Navy FAQ says initial review and modifications are used to minimize potential public-safety and environmental impacts.

What happens during a non-explosive sea trial?
A sea trial provides conditions that a land facility cannot fully supply. In the U.S. Atlantic Fleet draft review, non-explosive torpedo testing may involve aerial, surface, or subsurface platforms firing exercise weapons at surface or subsurface targets, or conducting a run with no target using programmed geometry. The platform, target, and test design depend on what is being evaluated.
The September 2024 review lays out proposed Phase IV activity for 2025–2032 in named range complexes, including Northeast, NUWC Newport Testing Range, Virginia Capes, Navy Cherry Point, and Jacksonville. Its draft parameters describe events lasting up to two weeks, with up to 40 torpedoes and typically no more than eight per day during daylight hours. These are planning parameters in a draft environmental review, not confirmed firing records or limits that apply to other programs.

How are exercise torpedoes recovered?
For the non-explosive AFTT activity, the review says the exercise weapons are recovered, typically by surface ships and helicopters specifically crewed and equipped for recovery. Recovering them allows the Navy to examine the weapon and its stored data rather than treating every exercise firing as an expendable test.
A separate U.S. Navy report on submarine tenders says at-sea recovery capability gives commanders more flexibility in choosing firing locations; the usual alternative it describes is an established range served by shore-based small boats or helicopters. The report says recovered torpedo guidance-system data can be analyzed and describes successful exercise firings as part of the process before conversion to a payload-capable weapon. That account describes the U.S. Navy practice covered by the report, not a universal procedure. The Navy’s tender report explains the recovery role.

A training example shows one recovery arrangement in use: in March 2022, U.S. Navy aircrews and Japan Maritime Self-Defense Force units trained in Tokyo Bay with an inert torpedo that the JMSDF recovered. The Navy’s account of the exercise describes a specific training event, not a general development-testing procedure.
What safety controls manage risk at sea?
Using an inert weapon is one risk-reduction measure, but the U.S. Navy says inert practice munitions are used “to the extent possible” and cannot completely replace testing in a live environment. Its FAQ describes precautions for tests, including tests involving in-water explosives:
Best Value
- Fully engraved panel lines
- Detailed cockpit with pilot figure
- Accurate fuselage machine gun turret
- Detailed landing gear
- Desktop display stand included
- Use established operating areas and conduct environmental and safety reviews before tests on range sites.
- Ensure impact areas and targets are unpopulated; postpone or cancel activity when safety concerns warrant it.
- Notify the public of a test’s location, date, and time, and impose temporary access restrictions where appropriate.
- Issue notices to mariners and pilots. The Navy FAQ says Coast Guard notices give mariners information about location, activity, and duration.
The FAQ also describes designated operating, warning, and restricted areas in marine waters and airspace. Those boundaries, notices, reviews, and cancellation options are layers for managing exposure; a notice alone does not make an activity safe, and none of the measures guarantees zero risk.
Can an uncrewed vehicle launch a torpedo?
In a trial reported September 30, 2026, the Royal Navy’s XV Excalibur extra-large uncrewed underwater vessel fired and controlled a U.S. Navy Mk48 Mod 4 heavyweight torpedo at the British Underwater Test and Evaluation Centre near Kyle of Lochalsh, Scotland. The three-week experiment used an inert, recoverable torpedo. The Royal Navy said the uncrewed approach could reduce risk to personnel.
This was one trial, not evidence that crews have been removed from torpedo testing generally. Uncrewed launch platforms are one additional way to reduce personnel exposure in some activities. The Royal Navy’s announcement describes the platform, weapon, and trial.

Land-based chambers can answer selected questions before a weapon goes to sea. Non-explosive exercise firings can evaluate torpedo performance and upgrades without an in-water explosive, and recovery enables inspection and analysis. Ranges and safety procedures help control where and when tests take place. But inert trials cannot replace every realistic test, and the examples above establish procedures for particular U.S. Navy programs and one Royal Navy experiment—not a worldwide standard.
