Poland has extended the service life of its two Oliver Hazard Perry-class frigates until 2024. That reports Janes.
The prolonged service time has required some additional maintenance work and upgrades of subsystems. ORP General Kazimierz Pulaski has already completed these works during a scheduled docking. This includes the installation of Link 16 and an upgrade to the command system to allow automatic detection and tracking of aerial and surface targets. The 76 mm. gun (Mark 75) has been replaced with a refurbished analogue. Fire control systems, radar, and generators have been updated, and the Mk 13 missile launchers have been upgraded to mod 4 block 6 standards. The SM-1 air defense missiles have been upgraded, and the ship has received more modern electronic warfare equipment and air defense systems.
There is also equipment which is not upgraded, and in order to ensure the prolonged service life of the ships, the use of some systems like the Phalanx 20 mm close-in weapon system has been restricted.
The other frigate, ORP Tadeusz Kosciuszko is expected to receive the upgrades in the second half of 2018.
These upgrades give a substantial lift to Poland’s frigates. However, it is not cutting edge technology, and 2024 is not far away in the grand scheme of things. So Poland will still have to think about possibilities for a renewed frigate capability.
