send the last F/A-18 A-D to the boneyard no later than the fiscal 2030 timeframe. Boeing is also working with the Navy on a reset of the Super Hornets environmental control system following a spike in hypoxia-like physiological episodes in the fleet. They are designed to replace the extra fuel tanks the Super Hornet currently slings under its wings, reducing weight and drag and enabling additional payload.Finally, the Block III upgrade also will include a long-range irst sensor that will allow the Super Hornet to detect and. The Navy will begin procuring the Block III Super Hornet in fiscal 2019 with a 24-aircraft buy, the first of which will come off the production line in 2020. Later, SLM will incorporate efforts to make the aircraft more maintainablefor example, grooming wire, fixing corrosion and replacing ducts. Boeing will achieve this goal both by building new Super Hornets and by upgrading the older Block II aircraft to the Block III configuration i -depot.

Boeings Next-Gen Super Hornet Will Be (Sort Of) Stealthy Lara Seligman ".Gillian Dan Gillian, Boeing F/A-18 and EA-18 program manager confirms that an improved low-observable (LO) coating will be one of five key characteristics of the Block III Super Hornet. Meanwhile, the Navy will accelerate divestiture of the legacy Hornets, with the last active component squadron transitioning to the Super Hornet in 2018. This drove Boeing to drop certain features of the 2013 proposal, such as an enclosed weapons pod and internal infrared search-and-track (irst) sensor, from the newest package. But there are other ways to enhance stealth, such as adding LO coating and radar-absorbent material improvements in certain locations on the airframe. Boeing engineers found they needed to make design compromises to significantly reduce the aircrafts radar cross sectionfor instance, by restricting payload, Gillian told Aviation Week in 2017. The CFTs will extend the range of the aircraft by 100-120. Over the next five years, the Navy proposes buying 110 additional Super Hornets, including a three-year procurement, which is a significant boost from last years budget request. Boeing intends to start service life modification (SLM) work on the Block II aircraft. The fighter is already a very stealth airplane todayhe says, declining to elaboratebut there are new coatings engineers can apply on different surfaces of the aircraft to make it even more survivable, he says. The F/A-18 was not designed specifically to be stealthy and lacks many of the fundamental stealth characteristics baked into Lockheed Martins F-35 and F-22 airframes.
