You will never find a "static" figure for this. Moreover, RCS of aircraft is a complex phenomenon, depending on many stuff (frequency, aspect angle, polarization of signal etc). Jordan Castelan/US Air Force Various reports have suggested that the H-20 could be equipped with either conventional or nuclear missiles, and would have. VHF radar should be able to detect them at long range. Even today, the B-2 continues to perform, inspire and pave the way forward. The B-2, a Northrop Grumman engineering marvel and legendary aircraft, spelled a quantum leap for technology and American air superiority. Stealth aircraft have low visibility on radar. Jmarked 30 years since the B-2 Spirit first took to the skies and became our nation’s premier long-range strike bomber. Moreover, stealth aircraft generally operate during night when contrails are less visible. Ergo, until the stealth aircraft is really close (assuming it is on a SEAD/DEAD mission) one cannot see the contrails and by the time they do, it is too late. That being said, it is essential to remember that though contrails are visible to the naked human eye they are NOT visible to Radars. Ophir's Pilot Alert System which is used by the B-2 stealth bomber uses LIDAR (light detection and ranging) to differentiate contrails from clouds and tells the pilot to change his altitude as/when necessary. A tried and tested method by NASA is NOT to fly in regions of air that support contrail formation. Contrails form due to moisture in the aircraft's exhaust. Not just stealth aircraft, most military aircraft are required to avoid contrails. The B-2 Spirit stealth bomber is one of America's most secretive weapons, but this week, for the first time in the three-decade history of the program, the US Air Force gave viewers a first look.

Do stealth airplanes need to limit contrail generation?
