All armor composed of HSLA-100 Steel, the new Naval steel which is stronger than conventional carbon steel, and has a yield of 150 ksi.

The hull is a double hull design. The between hull space is filled with kevlar bricks, to prevent armor splintering and protect further against shaped warheads.

Armor is sheeted with a Titanium layer.

SPY-3 with Aegis Mk7 Baseline 7.0b/CEC
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.

Rear Helo-deck can accomodate x3 AH-1 Super cobra gunships, however no hangar space is available to store them. Or a single Chinook can land for utility and cargo purposes. A cargo hatch is located just at the end of this Helo-pad. Munitions and cargo can be loaded directly to and from the helo-pad, and then transported to the munitions bunkers through a cargo lift located in this cargo bay.
