As a result of efforts to achieve economies of scale, the PAAMS command system shares a common architecture with that of the Type 45 destroyer. Consequently, the PAAMS uses the same Windows 2000 based command consoles as the Type 45. This extends the use of Windows for Warships outside the Royal Navy to the French and Italian navies as well. On 28 January 2009, the PAAMS was given its official designation of Sea Viper by the Royal Navy.
Hey, no problems, the Sea Viper missiles are Windows based...:^)
