Another Tailhook video
OpNAV panel https://livestream.com/wab/tailhook2017 ... /162483994

-- 07:00 - Bill Swan (APW TacAir USMC) - F-35B info
-- 12:30 - F_35C USN Status
---- 3 F-35Cs already loaded with Block 3F
---- Aug 2018 goal for F-35C IOC
---- Previously mentioned "fixed" to cat oscillations well received
---- OLED HMDS looks to be on track
---- Aim-9X outer wing panel fix is looking good too
---- F-35 generates nearly a terabyte of downloaded date per flight.
---- F-35C has been flying TopGun for two years.

Is the C going to be able to perform high AOA maneuvers like we saw from the F-35A at the Paris airshow? I already know about the poor acceleration issues. Hoping with a more powerful engine they can take some of that back, but the C seems to be the least agile of all the variants.

OTOH, it should be able to turn tighter given its greater wing area?

There should be no reason for it not to be able to do the same AOA as seen on the F-35A.

I disagree with this statement. It may have the worst climb and acceleration but it will be the best turner and have the best low speed handling. When the Sust G spec took a hit the C took the smallest hit and was still listed as the highest of the three. Previous analyses of mine show that it should have the best ITR at operational altitudes as well due to the big wing. It will be just fine.

Is that a question given the information in this thread and elsewhere? Please clarify the question re 'kind'.

I think he said GBU-32's by mistake, and i think those are GBU-31's by the visual size..i'm not 100% sure.

Your comment implies that not all Nimitz class carriers have four wires.

F-35C High AOA testing

sprstdlyscottsmn is right; the CV F-35 has no problem with low-speed handling and turns.

That is correct 'not all Nimitz class carriers have four wires' the video mentions this while the last two NIMITZ CVNs had only three wires, with 3A being a barricade installation OR a backup No.3 wire (this unused sheave is adjacent to No.3 sheave) as per several diagrams / articles on this and other threads. Here is a recent diagram:

F-35C Carrier Suitability Testing Explanation from CMDR Tony Wilson FIRST F-35C deck lander TEST PILOT PDF 44 pages.
F-35 Carrier Suitability Testing
17 May 2018 Tony Wilson

"Carrier Suitability is a multidiscipline specialization of aircraft test and evaluation. The discipline combines theories from aircraft loads, flying qualities, and performance in a system of systems approach to assess the suitability of an aircraft to operate from ships and austere sites. Additionally, navigation and guidance, sensor integration, data link interoperability, pilot-vehicle interface, supportability, and maintainability are evaluated to ensure the aircraft is capable to operate as a system within a system. This paper will provide an introduction to carrier suitability flight test of the F-35C, a carrier-based, multi-role, 5th Generation stealth fighter to be used by the U.S. Navy and U.S. Marine Corps. Topics will include a discussion of the shore-based testing prerequisites and results, an overview of the challenges experienced with the original tailhook and its redesign, and the use of autopilot functionality in shore-based testing. This will be followed by an examination of the necessity to test in the shipboard environment, a discussion of shipboard testing, shipboard catapult and arrested landing methods of test and results. Throughout, an investigation on how advanced approach mode control laws used for shipboard landings were implemented, the results from three ship trials, and the implications to future operations will be analyzed."
