Turkish systems engineering and design house STM Savunma Teknolojileri Mühendislik ve Ticaret A.Ş. (Stand B-050) is to lead the programme for the mid-life upgrade (MLU) of the Turkish Naval Forces Command’s four Type 209/1400 Preveze-class submarines.
Under the terms of the contract, signed with Turkey’s Presidency of Defence Industries (SSB), STM will take on the role of lead partner in partnership with Havelsan, Aselsan and Asfat.
The four Preveze-class boats were delivered between 1994 and 1999. STM says the four submarines will re-enter service in 2023, 2024, 2026 and 2027.
