AU British Hovercraft BH.7 Mk 20 of Royal Hellenic Navy:
Although they are capable of taking anti-ship missiles, these hovercrafts in RHN have mainly logistic support role. Order came in 1980 for 10 units of which 6 were built under license. Their armament is twin 30mm cannons, 32 X 128 mm unguided rockets in 2 X 16 configuration (for engagement of the area targets on the shore before landing) and twin SADRAL, which replaced Sea Cat in early to mid 1990's. The 30mm cannons are LS-30 with a locally designed cover from reinforced plastic to avoid salt and sea spray affecting the cannon.
Propulsion is 1 X 6,000 hp Allison 570K.
Rocket launchers were specially developed to be as light as possible, but strong enough as well. The launcher also has cap in both sides to prevent problems from sea spray and salt. Several types of rockets are available.
Royal Hellenic Navy AU has a large hovercraft fleet consisting from British and Russian origin types, plus a locally developed one for entering LPH and LPDs. That was developed and built from mid 1980's to late 1990's, using experience from license manufactured British hovercrafts. The fleet includes also 6 Zubr hovercrafts.
