USMC's Electronic Warfare Effort....Across various platforms based on the Intrepid Tiger II....

 Marines assigned to Marine Medium Tiltrotor Squadron 264 (Reinforced), and 2nd Radio Battalion Detachment, 22nd Marine Expeditionary Unit (MEU), prepare for departure to conduct the first operational flight of the Intrepid Tiger II (V)3 Electronic Warfare pod aboard the amphibious assault ship USS Wasp (LHD-1). The Intrepid Tiger II EW is a network-enabled family of systems that provides a RDC (Rapid Deployment Capability) to support ground combat operations. 22nd MEU, deployed with the Wasp Amphibious Ready Group, is conducting naval operations in the 6th Fleet area of operations in support of U.S. national security interests in Europe.

A quick Google search and this is it.   This is how the USMC is planning on conducting EW into the future.  As I suspected it involves using the F-35B's AESA array but also the little jewel you see above.  Never heard of the Intrepid Tiger II but that's what they're betting on.  We'll see if it pays off but uncharacteristically the USMC is deviating from the Navy plan...and for now the Navy is allowing it.

Time will tell.
