why does the phantom 3 advanced get better range than the phantom 4?

These modernized RF-4Cs of the Alabama and Nevada Air National Guard extensively participated in the Gulf War 503 built. Additionally, the RF-4Cs of the Alabama, Nevada and RF-4 Fighter Weapons School were modified to carry the AIM-9 Air to Air Missile. While usually unarmed, RF-4Cs retained the ability to carry a nuclear weapon on the centerline pylon. A sub-variant, to be designated RF-4C(H) was proposed as a night 'hunter' aircraft using infrared equipment instead of cameras under Operation Shed Light. Many aircraft were refitted with a more spacious bulging streamlined nose. Equipped similar to RF-4B but with a wider choice of camera fits, including a centerline pod for the gigantic HIAC-1 LOROP (Long Range Oblique Photography) camera, capable of taking high-resolution images of objects 100 miles (160 km) away. RF-4C All-weather tactical reconnaissance version for the US Air Force, AN/APQ-99 (later AN/APQ-172) radar. Ī Kentucky ANG RF-4C showing camera installations and drag chute. In 1975, modernized under Project SURE (Sensor Update and Refurbishment Effort) 46 built.

The KS-72 or KS-85 cameras were on rotating mounts and could be aimed in flight which improved upon the earlier RF-4C which could only be aligned on the ground. Also carried AN/APQ-102 reconnaissance SLAR, AN/AAD-4 infrared reconnaissance system, and ALQ-126 ECM suite. Three camera bays typically carried KS-87 forward oblique/vertical camera on Station 1, KA-87 low-altitude camera on Station 2, and KA-55A or KA-91 high-altitude panoramic camera on Station 3. F4H-1P (RF-4B) Tactical reconnaissance version of F-4B for United States Marine Corps, nose stretched 4 ft 9 in (1.4 m), smaller AN/APQ-99 radar. QF-4B F-4Bs converted into unmanned supersonic target drones 25 converted. NF-4B The redesignation of one F-4B for testing purposes. EF-4B One F-4B converted into an ECM training aircraft. DF-4B F-4Bs converted into drone control aircraft. J79-GE-8A or -8B engines with 16,950 lbf (75.4 kN) of afterburner thrust each.

F4H-1 (F-4B) Two-seat all-weather carrier-based fighter and ground-attack aircraft for the US Navy and Marine Corps. TF-4A A small number of F-4As converted into two-seat training aircraft. Named Phantom II in 1959 and redesignated F-4A in 1962 45 built. F4H-1F (F-4A) Two-seat all-weather carrier-based fighter for the US Navy, J79-GE-2 and -2A engines with 16,100 lbf (71.6 kN) of afterburner thrust each. XF4H-1 Two prototypes for the United States Navy, first flown 1958.
