Whether the modification of the targeting method of the guided weapon affected the range of the AGM-62A

When I drive the A7E and throw the AGM62A. I found the AGM-62A’s lock-in distance to ground targets reduced from the original 6KM to 2-3KM, which was incredible. 10.7 The use of 3KM range guided bombs does not provide any survivability or attack efficiency, which should be noted by developers
