Mid-life upgrade

The three vessels went through a mid-life upgrade between 2015 and 2017, and are now expected to serve until the 2030s.

The upgrades included new main and auxiliary engines, as well as a new high-pressure fire extinguishing system.[3]

The vessels were also equipped with a Saab Trackfire RWS with a 7.62mm PKM machine gun and a 40mm Heckler & Koch GMG. The two Sako twin-barreled 23 mm/87 (modified ZU-23-2) were removed.

gollark: Oh look, styro just entered the diode cult.
gollark: I could understand "hardware card thing with a bit of data on it", but SIMs actually run quite complex and often exploitable software.
gollark: eSIMs are *still hardware devices*. Just programmable ones. Which is... why.
gollark: What do you mean? Should you not have planned this before?
