Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
15,927 lbs / 7,225 Kg = 147.5 x 6.0 " / 152 mm shells or 2.6 torpedoes
Stability (Unstable if below 1.00): 1.07
Metacentric height 2.9 ft / 0.9 m
Roll period: 15.8 seconds

- Stern: 20.00 ft / 6.10 m
- Average freeboard: 17.32 ft / 5.28 m
Ship tends to be wet forward

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 64.6 %
- Above water (accommodation/working, high = better): 165.3 %
Waterplane Area: 26,093 Square feet or 2,424 Square metres
Displacement factor (Displacement / loading): 170 %
Structure weight / hull surface area: 80 lbs/sq ft or 392 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.06
- Longitudinal: 0.98
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

2000 tons - 1000 Troops and equipment.
500 tons - Heavy duty cranes
700 tons - 6 LCT/I (Landing Craft, Tank/Infantry)
320 tons - 8 LCVP (Landing Craft, Personnel)
300 tons - Tanks and vehicles
150 tons - Aircraft facilities
30 tons - Radar, Radio, C3



Its designed to carry any combination of these British landing ships:

Landing Craft Vehicle LCV (1): 36 tons, 48.5ft long, one 7.77mm Vickers, able to carry one 16 ton tank or 100 troops

Landing Craft Vehicle LCV (2): 50 tons, 50ft long, able to carry one 30 ton tank or 100 troops

Landing Craft Vehicle LCV (3): 63 tons, 60ft long, able to carry one 40 ton tank or 100 troops

Landing Craft Infantry LCI (1): 100 tons, 105x21.5x3.6ft (32x6.53x1.08m), two 420hp Hall-Scot petrol engines, 14.5kts, two single .661in Vickers HMG, 15 crew, 100 troops


So while in theory it can squeeze in 6 of the 600t LCIs, it would probably carry 4 100t LCI, 4 50t LCV, and 8 30t LCVPs.

Or alternatively a full MTB squadron of 6 boats.


So two of these can show up to any unattended atoll and voila, instant base.
