Our first look at the Stinger with Javelin FCU:

Interestingly there article mentions the LWCLU will have data sharing, and will allow launching both Stingers and Javelins from the same CLU. So units in the field will only need to carry one CLU to fire both missiles. 

Another advantage is the CLU will offer much better effectiveness at night compared to current MANPADS:

Downside of the LWCLU is that this will dramatically increase the cost of a Stinger, and make it harder to be mass distributed.
