Northrop F-5A Freedom Fighter F-5E Tiger II F-20 Tigershark Light Tactical Fighter



DESKRIPSI:

Northrop mulai proyek pesawat tempur ringan ini pada 1953 yang disebut dengan N-156F Freedom Fighter. Walaupun tidak dibeli oleh Militer AS, pemerintah AS mendukung penjualan 879 pesawat F-5A kepada 21 negara sahabat. 320 pesawat lain dibuat di bawah lisensi di beberapa negara lain. F-5E Tiger II muncul pada awal 1970an dengan mesin yang lebih bertenaga, kapasitas bahan bakar yang lebih besar dan pengembangan aerodinamisnya. Lebih dari 1400 pesawat ini terjual, termasuk beberapa dibeli oleh AL dan AU AS untuk program Tog Gun dan Aggressor untuk simulasi pesawat dan taktik musuh.

Pengembangan selanjutnya dari F-5 adalah F-20 Tigershark, yang similar performansinya dengan F-16. Akan tetapi, F-20 gagal menarik perhatian konsumen pada pasar pesawat tempur yang kompetitif pada akhir 1980an. Sekitar 2.700 pesawat ini dibuat untuk AS dan 30 negara lain dengan waktu produksi berakhir pada 1987. Mungkin varian F-5 yang paling terkenal adalah T-38 Talon yang merupakan pesawat trainer dua-tempat duduk yang digunakan oleh AU AS dan NASA.
