Simple airships were used as surveillance aircraft as early as the 18th century. Over the years, military aircraft have
been built to meet ever increasing capability requirements. Manufacturers of military aircraft compete for contracts to supply
their government's arsenal. Aircraft are selected based on factors like cost, performance, and the speed of production.
TYPES OF MILITARY AIRCRAFTS
* Fighter aircraft's primary function is to destroy other aircraft. (e.g. F-16, MiG-29, and the Mirage 2000])
* Ground attack aircraft are used against tactical earth-bound targets. (e.g. Su-25, A-10, and the F/A-18)
* Bombers are generally used against more strategic targets. (e.g. Tu-22, Tu-160, B-24, and the B-52)
* Surveillance aircraft have special capabilities used for reconnaissance (e.g. U-2, MiG-25R and SR-71)
