Do stealth planes have contrails?
Contrails would be a dead giveaway for a stealth aircraft. At typical contrail-friendly altitudes, between about 28,000 and 40,000 feet, temperatures run from about -36 to -76 degrees. If the airplane leaves a long trail, the air is not only cold but humid, allowing the ice crystals to persist.
Do stealth bombers leave contrails?
What’s clear, though, is if a stealth bomber leaves a contrail, the air force’s prized secret weapon becomes just another readily visible, albeit striking, high-altitude bomber. This much is known: the air force has grappled with the contrail problem from the outset of the B-2 program.
Is stealth aircraft overrated?
They argue that stealth is overrated and it’s better to buy greater numbers of cheaper, non-stealthy planes. The high expense of developing, buying and maintaining stealth jets means they may be used sparingly. Many stealth aircraft still have questionable ability. SEAD may be much cheaper than stealth.
Is stealth obsolete?
Stealth aircraft remain far from obsolete. The German aircraft radar imposes costs on the defender, forcing adversaries to buy expensive passive radar systems. It will be a long time before all countries have passive radars.
Why do military jets not leave contrails?
Why do some jets not leave contrails? Contrails form when jet exhaust emits water vapor that condenses and freezes. Contrails don’t form for every airplane. The atmosphere where the plane is flying needs to have low vapor pressure and low temperature.
What do you call the trail of smoke behind a jet?
The trails left behind by planes are officially called contrails, short for concentration trails. They form a bit similarly to how the breath you exhale can condense into vapor on a cold day.
At what altitude do planes leave contrails?
Exhaust contrails usually form at high altitudes; usually above 8,000 m (26,000 ft), where the air temperature is below −36.5 °C (−34 °F). They can also form closer to the ground when the air is cold and moist.
Is the SU 35 overrated?
The Sukhoi Su-35 is a version of the Su-27 fighter jet that has been deeply modernized to achieve a significant increase in its combat effectiveness against aerial, ground, and sea-surface targets. Nevertheless, the Su-35 takes the title of the most overhyped 4++ generation fighter aircraft.
Are there special equipment to limit the contrails of stealth aircraft?
To directly answer your question, stealth aircraft have no special equipment to limit their contrails. The military does though incorporate atmospheric data into their flight planning to minimize the creation of contrails especially during daytime operations.
When does a stealth aircraft have low visibility?
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. Moreover, stealth aircraft generally operate during night when contrails are less visible. Stealth aircraft have low visibility on radar. Not necessarily.
What causes contrails to form in the air?
Contrails form due to moisture in the aircraft’s exhaust. A tried and tested method by NASA is NOT to fly in regions of air that support contrail formation.
