New torpedo introduced into use in the Navy

The Navy conducted acceptance firings with the TP47 torpedo in the Archipelago Sea  on 31 October. Hamina-class fast attack craft PGG Pori and PGG Hamina conducted the first firings with the new torpedo model.

The TP47 is an upgraded version of the TP45 type torpedo delivered by SAAB Dynamics.  The TP47 and TP45 torpedoes are the same size, which enables the use of  the M/20 torpedo launchers, which were installed into the Hamina-class missile boats in conjunction with their overhaul, with both torpedo models.

The torpedo system was installed into the Hamina-class missile craft as part of the ongoing overhaul. The system was introduced into use with TP45 model torpedoes in 2020.

The propulsion, power supply and target homing systems of the TP47 now received have been modernized from those of the TP45.  The upgrade rendered the TP47 almost soundless and faster than its predecessor, easier to control and more advanced in terms of homing in on  a  predetermined target.

The TP47 is intended specifically for anti-submarine operations, but it is effective also against surface vessels.  The torpedo is capable of seeking and homing in on underwater targets autonomously changing its depth, speed and direction.  It is designed to operate in the Baltic Sea’s archipelago circumstances and shallow waters.

The same torpedo system will be installed also into the Navy’s upcoming Pohjanmaa-class corvettes.
