Usage in battles

In Simulator, the DB-3 has distinct pros and cons. It is a brilliant base / airfield-bombing plane with a maximum bombload of 1x 1000 kg + 2x 500 kg bombs, allowing it to easily finish a base or cripple airfield modules in one run. The bombs drop one by one, allowing flexible targeting. It has greatly improved handling and stability comparing with the previous SB2M, making flying a lot easier. However the DB-3 is quite slow, making it an easy target to pick on. It also has next to no defensive firepower: only 3x 7.62mm MGs in total; the one in the nose has great coverage, however most opponents are not likely to take head-ons. The top turret cannot even aim horizontally nor directly at the tail, meaning that the seemingly suicidal tactic of tailing a bomber can actually destroy a DB-3. The belly gun has good negative angle but its horizontal guidance is too limited. Therefore you can only target opponents at your front, upper half and lower rear.

When taking off, the DB-3 will shift to the right, so it is best to set separate keybind for left and right brakes to counter the torque. Given your weak guns, you can only survive if the room is rather empty or if the opponent also has weak firepower. If you are bombing a base, fly at treetop level to force any attacker to engage you from above so you can fight back. Bombing airfield is more dangerous, as you are not only exposed to AAA fire, but also attackers hiding in your gunner's deadzones. Climb to at least 2000m before approaching the airfield, then target the modules of fuel sector (surrounded by 4 towers), residential area (a bunch of tents) and hangar (6 giant houses). Bombing the airstrip is the easiest but it seems to give less rewards. If you see an attacker trying to shoot at you, you will have to nudge the plane so that the target is within your gunner's guidance which is very awful. The bullets will not do lots of damage as the target might constantly get into your deadzones. Most of the times against maneuvering or heavily armed / armored attackers, you will not survive long.

Landing is easy and similar to the style of the SB2M. Line up with the airstrip when it occupies around 1/3 of your windscreen and descent to treetop level. Cut throttle to around 0-40% to drop speed to 200 kph, and deploy landing flaps and gears. Control the throttle so that the touchdown speed is around 140kph. Like the SB2M, if you don't slow down enough the DB-3 will bounce off again and again which might lead to a crash. Once you have landed, you can keep braking as the nose will not dip down and cause a propeller strike.

Pros and cons

Pros:

• Great maximum bombload of 2 x 500 kg + 1 x 1000 kg bombs allows you to finish a base in one go, or even have spare bombs for other targets
• Has a wide range of bomb combinations, meaning that you can choose between large and small targets
• Can break continuously until full stop, its nose will never strike the ground
• Nose turret has wide coverage

Cons:

• Extremely weak defensive firepower: terrible gun coverage at the rear/bottom, you cannot aim at planes on your side, tail, or underside, gunners are unprotected, and the 7.62 mm MGs lack damage
• Quite slow and large, making it an easy target
• Below average climb rate
• Only has landing flaps
• Negative deflection of elevator will not pitch the plane down at >390 kph

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
