U.S. Navy Receives C-130J-30 for Planned E-130J TACAMO Mission
The U.S. Navy received a C-130J-30 from Lockheed Martin for the E-130J TACAMO mission, which will replace the E-6B Mercury. The aircraft will be modified by Northrop Grumman under a $3.46B contract. The GAO noted potential development risks, including operational-availability concerns and manufacturing difficulties. The critical design review is scheduled for late 2027, with no operational service date provided.
