Testing work on the AIM-9X Block II version began in September 2008. The Block II adds Lock-on After Launch capability with a datalink, so the missile can be launched first and then directed to its target afterwards by an aircraft with the proper equipment for 360 degree engagements, such as the F-35 and F-22. By January 2013, the AIM-9X Block II was about halfway through its operational testing and performing better than expected. NAVAIR reported that the missile was exceeding performance requirements in all areas, including lock-on after launch (LOAL). One area where the Block II needs improvement is helmetless high off-boresight (HHOBS) performance. It is functioning well on the missile, but performance is below that of the Block I AIM-9X. The HHOBS deficiency does not impact any other Block II capabilities, and is planned to be improved upon by a software clean-up build. Objectives of the operational test were due to be completed by the third quarter of 2013. However, as of May 2014 there have been plans to resume operational testing and evaluation (including surface-to-air missile system compatibility). As of June 2013, Raytheon has delivered 5,000 AIM-9X missiles to the armed services. In February 2015, the U.S. Army successfully launched an AIM-9X Block II Sidewinder from the new Multi-Mission Launcher (MML), a truck-mounted missile launch container that can hold 16 of the missiles. The MML is part of the Indirect Fire Protection Capability Increment 2-Intercept (IFPC Inc. 2-I) to protect ground forces against cruise missile and unmanned aerial vehicle threats. The X-model Block II Sidewinder has been determined by the Army to be the best solution to CM and UAV threats because of its passive IIR seeker. The MML will complement the AN/TWQ-1 Avenger air defense system and is expected to begin fielding in 2019.
In the olden days, did fighters have 20mm guns for air-to-air dogfighting……
Everyone talks about guns on fighters being a solid way to keep fighting when you're out of missiles, no one ever wants to talk about the fact that these guns fire for mere seconds and they're empty as well.

And in times after the Vietnam War, how important has the gun been in air-to-air combat?
