You are missing out on the funding crunch and the potential game changer F-16V upgrades depending on how well Pakistan plays its cards in washington.
F-16s need to soldier on as well and be brought up to long range 200km BVR standard as well.....plus if anything, Pakistan can utilize the current goodwill in Washington to get some strike weapons for F-16s as well.
My friend, your idea is impossible to achieve.
Currently, the longest-range missile equipped by the U.S. Air Force is the AIM-174B, which has a range of 350 km. This missile weighs 1.5 tons and can only be mounted on heavy aircraft, and it does not belong to conventional air-to-air missiles. China and Russia both have similar weapons, with ranges that exceed the American AIM-174B.
The current mainstay weapon of the United States is the AIM-120D, with a maximum range of 160-180 km. The AIM-260A has a range of over 200 km, but this missile is currently in the testing and early deployment phase.
There are three issues at present.
First, in October 2025, the U.S. agreed to sell AIM-120D missiles to Pakistan, which is now in the process of procurement and upgrades. However, the U.S. states that this missile has a range of 160-180 km, which does not reach the 200 km range you mentioned.
Second, Pakistan has confirmed the range data for the PL-15E, but the range data for the U.S. missile cannot be verified. After testing, the Pakistani military can determine the missile's real range. Currently, the U.S. has only agreed to sell the AIM-120D, but procurement, delivery, and testing are still required. It is foreseeable that for a long time we will not be able to see the real missile data for the AIM-120D.
Third, I do not believe the U.S. can develop an air-to-air missile with a range exceeding 200 km within five years. The reason is simple: the U.S.'s dual-pulse technology cannot be miniaturized. If dual-pulse technology were that simple, when India obtained the PL-15E debris, many countries would not have been so eager to acquire it.
Currently, the operational air-to-air missiles that use dual-pulse technology are only the PL-15, PL-17, and PL-XX.
