This is a bomber's top speed is around 500MPH, and it's equipped with dual bomb bays, cruise missiles, flare and chaff dispensers, and an autoturret in the nose. This plane's main defenses are its moderate top speed and its countermeasure dispensers that allow you to break missile locks and get out of range of AA fire from ships and ground batteries, respectively. For hostile aircraft that you can't outrun, you can use the nose turret to engage targets within a 60* firing cone in front of the aircraft. It's no dogfighter, but it's maneuverable enough with the gyroscope turned off to bring the nose turret to bear on most attackers long enough to disable or destroy them.

This bomber has a camera in the nose labeled "Bomb Sight" that makes it easy for you to see where your bombs will strike during a wings-level bomb run. While you can drop bombs fairly accurately at full speed, you may get a better spread if you reduce power as you approach the target.

The gyro is activated by default. The plane doesn't need the gyro to fly, but it helps hold the plane level during bomb runs and keeps the plane's pitch from changing abruptly when you're changing its COM by offloading a bunch of heavy munitions all at once, like when you unload a bomb bay or dump all of your cruise missiles. You can leave the gyro on for most things, and the plane will still perform basic maneuvers smoothly. You can turn the gyro off to get more maneuverability for evasive/defensive maneuvers or for finer control during final approach and landing.

Once you've selected one or more bomb bays, use the VTOL slider to open the bomb bay doors. AG1 engages the motors that open the forward bomb bay, and AG2 engages the motors that open the rear bomb bay. AG3 drops the forward bombs, and AG4 drops the rear bombs. If you accidentally drop bombs inside a closed bomb bay, they probably won't explode as long as you don't maneuver too abruptly, but you'll probably want to open the bomb doors to let them fall out instead of letting them jiggle around in the bay until they blow up.

The cruise missiles can quickly target any ground or sea target within their maximum range, regardless of the target's position within that sphere. In the event that you need to dump all of your cruise missiles, AG6 allows you to drop all of the cruise missiles at once even if you have no target selected. You may wish to dump your bombs and missiles and deactivate the gyroscope to gain more maneuverability for evasive maneuvers or to avoid having your plane destroyed by AA fire striking your munitions.

The nose turret is based on JoshuaW's Nose Autoaim Turret. It will automatically track targets within a 60* firing cone in the front of the aircraft. The autoturret can engage air, ground, and sea targets. I would've used the same basic turret as a tail turret if I understood the functions involved well enough to make it aim properly when oriented rearward, but I don't, so have fun using this plane's huge control surfaces to bring the nose turret to bear on hostile fighters that you can't simply outrun. This plane can soak up a fair bit of gunfire, but enemy missiles will bring it down in a hurry.
