SBD-4 Dauntless

   Hello everybody. I’d like to suggest the Douglas SBD-4 Dauntless for War Thunder. While the SBD-4 is indeed similar to the SBD-3, it had some minor changes, such as new propellers and radar equipment for surface vessel search. Hence, I believe the SBD-4 is a worthy candidate as either a battle pass trophy, event, premium, or squadron aircraft.

Key Characteristics

• Naval dive Bomber
• New 24-volt electrical system instead of the old 12-volt system (meaningless in the game)
• Installation of Air to Surface Vessel radar with a Yagi array antenna under each wing
• Retained 1,000-hp Wright R-1820-52 Cyclone engine
• A new Hamilton Standard constant-speed variable propeller, with the old spinner removed
• New electric fuel pump instead of a hand-operated fuel boost pump

History

In late 1942, Douglas introduced the slightly improved SBD-4. It was very similar to the SBD-3 but featured a new 24-volt electrical system, new Air-to-Surface radar through field modifications, a Hamilton Standard constant-speed propeller, and an electric fuel pump. All these changes impacted the weight in a minorly relative increase, making it a slightly slower version than the SBD-3.

The US Navy and Marine Corps began to receive new SBD-4s in October 1942. These SBD-4s would participate in Solomon Islands, Gilbert and Marshall Islands, and Mariana and Palau Islands campaigns before phased out by early 1944.

The Royal New Zealand Air Force also received 23 SBD-4s, and the 25th Squadron RNZAF used them in combat over the South Pacific before being replaced by F4U Corsairs.

A total of 780 SBD-4s were produced in the middle of the war before being phased out and replaced with SB2C Helldivers.

Conclusion | Why it should be in the game

   I made this suggestion to pursue more WW2 content for War Thunder. This particular model is a perfect candidate as either a battle pass trophy, event, premium, or squadron aircraft because the US aviation tree has no premium dive bomber. So, putting this SBD-4 as a potential premium dive bomber would be a nice equivalent to the premium Ju-87 R-2 Libya in the German aviation tree.
