This Thursday INSIDER Daily Digest has news on the engine replacement effort for the F-35 Joint Strike Fighter and more.

We start off with coverage of the F-35 engine replacement effort:

As the F-35 joint program office considers future propulsion system modernization options, General Electric is arguing for an F135 engine replacement the company says would outpace technology offered through an incremental upgrade approach.

The Navy/Marine Corps Expeditionary Ship Interdiction System (NMESIS) recently hit a target as part of a major exercise:

USMC test fires NMESIS during major exercise, validating design ahead of key milestone review

The Marine Corps says it successfully demonstrated its new robotically controlled, ship-killing ground vehicle during Large Scale Exercise 21, launching a pair of cruise missiles from an unmanned tactical vehicle in Hawaii and sinking an at-sea target, a significant development for the service's No. 1 ground vehicle modernization priority.

The Air Force is still working through the more than 60 responses it received to a second request for information surrounding an expanded MQ-9 Reaper replacement search from this past spring, a review that comes as officials work to upgrade the existing fleet:
