The "Jason" (Ιάσων) or Island Class LST was designed by Hellenic Navy and Athens University/Naval Studies in mid 1980's to replace WW2 and 1950's era LSTs. Main requirements for the new LSTs were to be capable of transfer up to 22 MBTs or APCs, IFVS, military trucks etc in all sea conditions of Aegean, Ionian or East Mediterranean plus 280-350 fully armed men. Another requirement was to be capable of mine laying. Nine ships built in two batches from 1987-1990 and 1991-1994, all identical. These are real ships of Hellenic Navy (L173 to L177), but in my AU world more built with small changes. Most significant change from real world is that all 9 ships were modernized in with new Combat Management System, received 2 SADRAL launchers, Oerlikon 35mm were modernized with AHEAD ammunition , new Fire Control System Sea Arrow Mk.3 MR and IR scope was fitted to their twin 20mm Oerlikon cannons. The 20mm cannons will soon be replaced by 30mm Remote Control Stations with Nexter M791 cannon. They are also known as "Samos" Class, because L174 Samos was the first unit commissioned into the RHN. That ship in real world is the lead ship of is class.

Type : Landing Ship
Classification : Landing Ship Tank
Shipyard : Hellenic Shipyards, Elefsis & Perama
Built : 1987-1994
Planned : 9
Built : 9
Active (2021) : 9

Ships in Class

L171 Crete
L172 Syros
L173 Chios
L174 Samos
L175 Ikaria
L176 Lesvos
L177 Rhodes
L178 Limnos
L179 Kos

General Specifications

Displacement : full load 4,930 tn, empty 2,770 tn
LOA : 380 ft 6 ft (116 m)
Beam (max) : 50 ft 2 in (15.3 m)
Draught (hull) : 15 ft 1 in ft (4.6m at stern at full load)
Propulsion : Twin Wartsila Nohab 16V25 diesel, 10,000 hp total
Screws : 2, variable pitch
Max Speed : 17 kn, service speed 14-16 kn
Range : 4,700 nm / 16 kn
Complement : 116-120 (plus 280-350 men)

Armament

1 X OTO Melara 76/62 76mm
2 X 2 X 35 mm Oerlikon GDM-A mod (AHEAD capable)
2 X Oerlikon 20/70 20mm
2 x SADRAL (6 Mistral missiles each0
1 X Mk25 GMLS, 24 missiles
2 C CM-127 chaff launchers
Aviation capabilities : Helipad for one medium helicopter up to 10 tn
Boats & landing craft carried : 4 X Motomarine LCVP-36F (originally), 4 X Watercat M12 (after MLU) of which one armed with 120mm NEMO mortar

The Watercat M12 was built under license in HLK, being its largest user with more than 100 units in service by RHN/Landing Ships Command.

I am sure that the Watercat M12 can be fitted on these LSTs, deck space is enough with minimal modifications. Davits and crane also need upgrades for lifting more weight and new beds for the M12 are also need to replace the ones for the Motomarine LCVP 36F. It also plausible for Watercat to modify the M12 for carrying in davits.

Nice, but it would be even nicer if You change these horrible propellers and perhaps swap the underwater red for some less gaudy shade. ;)

The OPV variant of the HSY-102 light frigate:

OPV 440 Class does not have missiles and ASW equipment, so weight was reduced by about 200 tons. Larger fuel tanks were installed for increased range and twin RR Spey SM-1C instead of SM-1A. Top speed is about 37 kn.

As seen in drawning, there is space underneath the helipad for a 11m RHIB or any USV with length up to 15m. Hangar is sliding like in the Lupo frigate and helipad structure is strong enough to support a 10tn helicopter, such as AS-332C1 Super Puma.

RHN has a quite large fleet of hovercraft, except for the ACV(HL) there are several older British types in service, including the BH.7 Mk20 and BH.7 Mk6. Both were ordered in late 1970's to mid 1980's - 8 units for each type - of which 3 first were built in UK and rest under license by Hellenic Hoverwork.

The MK6 had the role of hover fleet protection and secondary attack missions armed with Shorts Sea Cat 2 missiles, an 76mm OTO Melara Compatto and 2 MM38 or 4 HASM-1 anti-ship missiles. The Mk20 mission was logistic support (20tn useful load) and it was also armed with twin double HDSO Y1980/86N2 30mm guns. Actually this naval cannon was fitted on the BH.7 Mk20 "L156" & "L157" for trials as early in 1983-84, before officially in service in 1986. A/A weaponry were Sea Cat 2 again plus twin MRL 12128 (one in each side) in fixed angle with a large round deflector behind for firing against enemy positions before landing. 24 rockets carried, with range up to 20km. Also 10 BH.7 Mk4 ,with pennant numbers L135 to L144, with shorter hull and 14tn useful load were ordered in 1970's and served until well into the 2000's.
