The Navy Test-Fires the New Torpedo 47

Swedish Armed Forces

The Navy - 3 December 2025 kl: 15.00

Recently, the navy fired torpedoes from both a corvette and a submarine. The purpose of the firing was to validate the new lightweight torpedo, Torpedo 47, against relevant targets while also conducting a live firing from a submarine.

The northern wind has died down and the sea has begun to settle as the corvettes leave the harbor in the cold dawn. Today's mission: together with the submarine waiting below the surface, to fire the new lightweight torpedo system. In the corvette's combat information center, the ship's anti-submarine warfare officer has just launched a torpedo.

"Torpedo in the water, normal launch, wire running well," says the ASW officer into her headset on the ship's internal communication system.

Contact!

On their large screens, she and her colleagues can follow the torpedo's path toward the target. As it approaches, the torpedo's own sensors acquire the target.

"Torpedo, contact with target," says the ASW officer.

Seconds pass. The ship rolls slowly in the meter-high waves.

The target, a large barge, lifts a few meters from the explosion.

"Assessed hit on target," says the ASW officer, who lost contact with the torpedo the moment it detonated upon impact.

Tailored for the Baltic Sea Region

The tests are being carried out in close cooperation with the Swedish Defence Materiel Administration, the Swedish Defence Research Agency, and the manufacturer Saab. Captain(N) Robert Schöllin is head of the Navy's Materiel Office and responsible for new equipment. He follows the shot from the bridge of one of the corvettes.

"We are validating the new lightweight torpedo system, from preparations aboard the ship to detonation at the target, and I can say that I am satisfied and that the new system has full functionality," says Robert Schöllin.

Torpedo 47 is used by the navy's corvettes and submarines for anti-submarine warfare and surface target engagement. The new torpedo is tailored for the unique underwater environment of the Baltic Sea region.

"Compared with the previous Torpedo 45, Torpedo 47 has better performance in all areas. New propulsion provides longer range and higher speed. The torpedo has a new seeker and better effect," says Schöllin.

Simultaneous fire

At the same time as the torpedo tests, the navy also conducted a live firing from a submarine.

"Given the security situation, it is important that we regularly ensure the functionality of our most advanced weapons. It is also highly relevant to pressure-test new equipment throughout the entire chain with our platforms and personnel," says Rear Admiral Johan Norlén, Chief of Swedish Navy.

"This demonstrates our ability to deliver effect in the Baltic Sea region, which is a prerequisite for being able to maintain sea control, both independently and together with our allies," Johan Norlén concludes.
