Ling-Temco-Vought A-7 Corsair II

The LTV A-7 Corsair II is an American carrier-capable subsonic light attack aircraft designed and manufactured by Ling-Temco-Vought (LTV).

Variants

A-7A

First production version.

Early USN Corsair IIs had two 20 mm Colt Mk 12 cannons with 250 rounds per gun.

Maximum ordnance, carried primarily on the wing pylons, was theoretically 15,000 lb (6,804 kg), but was limited by maximum take-off weight, so the full weapon load could only be carried with greatly reduced internal fuel; equipped with AN/APN-153 navigational radar, AN/APQ-115 terrain following radar, and a separate AN/APQ-99 attack radar, 199 built.

A-7B 

Uprated TF30-P-8 engine with 12,190 lbf (54.2 kN) of thrust. In 1971, surviving A-7Bs were further upgraded to TF30-P-408 with 13,390 lbf (59.6 kN) of thrust; AN/APQ-115 terrain following radar in earlier A-7A is replaced by AN/APQ-116 terrain following radar; 196 built.

A-7C

First 67 production A-7E with TF30-P-8 engines.

TA-7C 

Two-seat trainer version for USN, 24 converted from A-7B, 36 from A-7C. In 1984, 49 airframes, including the 8 EA-7Ls, were re-engine with the TF41-A-402 and upgraded to A-7E standard.

A-7D 

Version built for the USAF, more powerful Allison TF41-A-1 turbofan producing 14,250 lb (63.4 kN) of thrust, and a single M61 Vulcan 20 mm rotary cannon; Improved AN/APN-185 navigational radar, upgraded AN/APQ-126 terrain following radar; 459 built.

A-7E 

Effectively an A-7D modified for Naval operations; with the same Allison TF41-A-1 and M61 Vulcan 20 mm rotary cannon and further improved AN/APN-190 navigational radar and AN/APQ-128 terrain following radar in addition to arrester gear and folding wings to allow for carrier operations. 529 built.

YA-7F Strikefighter

(A-7D Plus) 

Stretched, supersonic version of A-7 powered by an F100, optimized for interdiction role, but cancelled after two prototypes were built.

A-7G

Proposed version for Switzerland, none built.

YA-7E/YA-7H 

Two-seat prototypes built by Ling-Temco-Vought as a private venture.

A-7H 

Modified A-7E for Greece without air-refuelling capability, 60 built.

TA-7H 

Two-seat trainer version for Greece.

A-7K 

Two-seat trainer version for Air National Guard, 30 built.

EA-7L

8 TA-7C modified into electronic aggressor aircraft used by VAQ-34, upgraded to A-7E standard while retaining twin seats in 1984.

A-7P 

Ex-USN A-7As rebuilt for Portuguese Air Force, 44 refurbished with TF30-P-408 engines and an avionics fit similar to the A-7E.

TA-7P 

Two-seat trainer version for Portuguese Air Force

Six converted from ex-USN A-7As.
