True. I don't believe they're flying them to integrate into the USMC fleet, but as written here, parts only. For the USMC, every AV-8 lost, there are no attrition replacements. The loss of the 8 or 9 of VMA-211s fleet in Afghanistan from the ground attack was a pretty devastating blow to the fleet, as a USN/USMC squadron generally has 12 aircraft. The blow was somewhat mitigated, when the Yuma MCAS-based VMA-513 was decommissioned and shut down just last month; which is very odd as it was the first USMC AV-8A Harrier squadron back in the day, introducing the jet to the USMC in the early 1970s. But the closure of the squadron, allowed 12 more jets to be redistributed around the fleet.
