Mk48 mod3 launcher
The Mk48 mod3 is designed for ships of less than 1,000 t displacement and is a compact module of six starting containers with a gas outlet upwards (see diagram), placed on the ship's deck.
This type of PU is fitted with corvettes of the Dutch Navy's Flyvefisken type and corvettes of the Danish Navy's Niels Juel type (see photo1).
