The GWS-24 Sea Cat SAM is located over the Hanger on the Stern of the Type 21 Frigate: https://edmundfovargue.artstation.com/projects/q9VaEn

Tigercat SAM with Missile Casings (Please note; I didn't make the Tigercat SAM model, just the casings and Sandbags in this Render, More Info: https://www.artstation.com/artwork/48rXl8 )
My model of the GWS-24 Sea Cat Surface-to-Air Missile (SAM) Launcher. This was an obsolete, subsonic CLOS SAM system by the Falklands war but even so, was still being used on many ships including the Amazon Class Type 21 Frigate.
The Launcher comes to 1,460 triangles, without Missiles, and has its own 1024 x 1024 Diffuse & AO, Specular and Normal Textures.
While the Sea Cat Launcher was totally my own work, the Missile wasn't totally made by myself, although I did fix it up, UV it, Texture it and make the LODs. It was instead made by lucky.BOY over at Project Reality for his Tigercat SAM, the land-based version of the Sea Cat, more info: https://www.realitymod.com/forum/showthread.php?t=140442
The Missile consists of 218 tris and has its own 1024 x 1024 textures (but in PR we have downsized this to 512 x 512).
The Sea Cat Missile Casing I made as a prop for both the Sea Cat and Tigercat SAMs as both commonly had them scattered around the launcher, on the Type 21 Frigate refs from the Falklands war show them scattered around the backup aiming sight as I have done on my Frigate.
Each Missile Casing consists of 282 tris and has its own 256 x 512 textures.
