The Singapore Sling

Singapore has ordered another 20 AIM-9X Block II Sidewinder and 100 AIM-120C7 AMRAAM air-to-air missiles for its 98 American F-15 and F-16 fighters. The AIM-9X-2 is the latest version of the Sidewinder, a missile that has come a long way since it first appeared in the 1950s. The 9X-2 can lock-on-after-launch. That is, the missile can be fired and then directed to a target via a datalink.
