Triton-1

Triton-1 is a compact Soviet underwater craft from Project 907 now resting at the Museum of the World Ocean in Kaliningrad. The hull is made from an aluminum-magnesium alloy, which keeps the weight low and allows for rapid dives.

The craft was built in Leningrad in 1972 as part of a production run of about 32 units intended for covert missions. It remained classified for many years and only reached the museum in August 2016 once secrecy rules were relaxed.

The name Triton comes from Greek mythology and refers to a sea creature associated with deep waters and exploration. Visitors today see the submarine as part of a broader display about marine technology and naval heritage along the waterfront.

The craft sits in an open display area near the museum and is currently being restored. Visitors can walk around it and examine the outer construction closely, though the interior remains off limits.

The crew worked in a flooded interior and wore diving suits with breathing gear for the entire mission. The craft could rest on the seabed for up to ten days waiting for orders while staying completely hidden.
