-change the number of the ships from 1 and 2 to 441 and 442

The first plan Royal Thai Navy need to install Phalanx CIWS , ESM Elettronica ELT 211 and ECM Elettronica ELT 318. i thinks they cut off because the budget.



look overload with 8 harpoon missiles and Phalanx.

Wow! Fantastic work!

Minor stylistical thought - on photographs it seems the main mast and funnel are square with rounded edges, while You have made lighter/darker shading 2-pixel thick (each), which, at least to me, implies it being rounded. IMHO 1 pixel-thick of shade would suffice.
Regardless of this, great work! Keep it up!

Bravo Zulu Superboy! Brilliant work and arguably the RTNs best non-helicopter capable Warship in its current fleet.

eswube, thanks. do you mean shading for the main mast? this ship more difficult for me because she has many detail in 76.82m.

squizzy,Hood,seeker36340,Trojan thank you. i don't have the badge of the ships so i will show the picture

thats one of the most easy things to fix. It, is just to remove one of the two lines (both dark an light) shading that is vertical. Can't explain it better, are at work.
