The STM 500 is a Turkish mini submarine of the 500-tonne class under construction since 2022. The shallow-water diesel-electric submarine is being built by Turkish defense company STM with completion of the first vessel not expected until 2026.[1]
As of June 2022[update], the customer for the project had not yet been publicly released.
History
The STM-500 was announced in 2021 at the 10th Naval Systems Seminar in August 2021 as a lower cost and more cost effective subsurface warfare option.[2] Construction began in 2022. It is expected to require four years to complete construction, and up to six years to fully complete the project.[1]
