This was drafted using naval engineering software. The survivability data can accomodate for cruise missiles too. Find out how many lbs of explosives the missile you want to compare with has and apply it to the number given under survivability. Kinetic impact doesn't matter in this data, since that figure will give you the number of penetrating hits needed. To find out if the missile will even penetrate the armor go here and use the formulas given.

Fairly easy math.

The eoxcet can penetrate 2.75" of steel. And my ship can take... 13 exocet missiles hitting in non critical penetrating manners.

Peripheral Vertical Launch System-
The solution consists of 50 four-cell PVLS situated round the perimeter of the deck, rather than the usual centrally located VLS. This would reduce the ship's vulnerability to a single hit.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
17,066 lbs / 7,741 Kg = 8.3 x 16.0 " / 406 mm shells or 3.2 ADCAP torpedoes

Seaboat quality (Average = 1.00): 1.08

Hull form characteristics: Tumblehome Hull
Hull has a flush deck
and transom stern
Block coefficient: 0.591
Length to Beam Ratio: 7.73 : 1
'Natural speed' for length: 28.51 kts
Power going to wave formation at top speed: 78 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 0.00 ft / 0.00 m
- Forecastle (20 %): 0.00 ft / 0.00 m

Ship tends to be wet forward

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 133.0 %
- Above water (accommodation/working, high = better): 67.0 %
Waterplane Area: 36,478 Square feet or 3,389 Square metres
Displacement factor (Displacement / loading): 126 %
Structure weight / hull surface area: 244 lbs/sq ft or 1,189 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 2.17
- Longitudinal: 0.90
- Overall: 1.12
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate

The radar suite will consist of a dual band radar for horizon and volume search, an L-band volume search radar (VSR) integrated with the AN/SPY-3 multi-function radar already being developed by Raytheon for the US Navy. The two radars are to be integrated at waveform level for enhanced surveillance and tracking capability. The AN/SPY-3 Multi-Function Radar (MFR) is an X-band active phased-array radar designed to detect low-observable anti-ship cruise missiles and support fire-control illumination for the ESSM and Standard Missiles.

Propulsion:
I've equipped my vessel with MERMAID electrical pods, these give the vessel 360 degrees of movement without a rudder and can operate independantly. Direct hits can no longer disable a rudder or prop. shaft. Greatly increases survivability and fuel efficiency.

6 Alstor MERMAID electrical pods @30MW each
Cruise Speed: 31 kts
Top Speed: 41 kts
