Game Tips:

Tip 1:

Because the F-22 Raptor employs LOST (low observable stealth technology), it's always a good idea to reduce the RCS (radar cross section) of the aircraft as much as possible. Most of the time, you should fly with your radar turned off while maintaining a cruising speed of around 400 to 500 mph (approximately 90 percent thrust).

Tip 2:

Refrain from carrying ordnance on your aircraft's external hardpoints. Weaponry mounted underneath your wings will increase the RCS of the aircraft, making it much easier for enemy radar installations to track your aircraft.

Tip 3:

Your wingman is particularly adept at taking out SAM (surface-to-air missile) batteries. For that reason alone, you should let your wingman concentrate on the destruction of any SAM sites within the objective area while you eliminate any radar installations
