A design ahead of its time but underpowered, and hampered by the abilities of its powerplants earning the nick name "Gutless Cutlass"

Undermined too (for example) by senior pilots who thought they knew better and didn't use high-lift devices on take-off/landing. It's a type that has earned a largely undeserved reputation.
 
A total of 320 Vought F7U Cutlass aircraft were built. Over 25% were destroyed in accidents thats over 80 aircraft! It had the worst accident rate of any US Navy swept wing aircraft in that era.
I think this article points out it was more than piolts who thought they knew better:

The main causes of the high accident rate with the US Navy Cutlass aircraft were underpowered and unreliable engines and an unreliable hydraulic system, which led to issues like flight control failures and landing gear collapse. These mechanical problems were compounded by the aircraft's poor stall characteristics and its inability to handle the high stresses of carrier operations, earning it the nickname "Ensign Eliminator".

Mechanical and engineering failures
  • Underpowered engines: The Cutlass was equipped with Westinghouse J34 turbojets that were significantly underpowered for the aircraft's needs, leading pilots to dub it the "Gutless Cutlass".
  • Unreliable hydraulic system: All flight controls were hydraulically powered, but the high-pressure system was prone to frequent failure, causing crashes and loss of control.
  • Weak landing gear: The nose landing gear was particularly weak and prone to failing under the high stress of carrier landings, often resulting in spinal injuries to the pilot.


Flight and handling issues
  • Nasty stall characteristics: The aircraft was prone to a violent tumble after a stall, and normal recovery procedures did not apply, making it a dangerous aircraft to fly near its limits.
  • Unreliable ejection seats: Some models also suffered from an unreliable ejection seat system.

Operational and maintenance problems
  • Carrier operations: The combination of weak landing gear and underpowered engines made taking off and landing on aircraft carriers extremely hazardous.
  • Maintenance intensive: The complex and unreliable systems made the aircraft maintenance-intensive.
These numerous design and mechanical flaws made the Cutlass one of the most accident-prone aircraft of the jet age, leading to its retirement in 1959, just a decade after its first flight.

I think you are relying on too much plagiarized information, lacking in primary-source reference; possibly from the never-to-be-trusted Wikipedia.

I suggest you refer to Tommy Thomasson/Al Casby's recent book, which goes into a great deal of detail as to why (for example) the aircraft could not be correctly termed "most dangerous" and compares the type more objectively to other types while citing the much-needed primary sources.

Al Casby is restoring an F7U to airworthiness and knows more about the type than anyone alive; he speaks as someone who truly knows the aircraft, not one who is unquestioningly repeating Wiki-derived BS.

320 built 80 accidents, Ensign Eliminator, GutlessCutlass, and your assuming Wikipedia.... Please inform us and lets hear your glowing critique on this aircraft. I stand by its well known terrible history, which speaks for itself.25 pilots killed 4 test pilots.

......and this is from the massive, 380+ pages "Vought F7U-3 Cutlass" by Tommy Thomason & Alfred Casby 2024.
I'd highly recommend the Thomason/Casby book: it corrects many a myth (QED) and puts the whole programme into context, using a great deal of primary sources. It's high on fact and avoids the usual lazy plagiarized errors.
 
I knew several Cutlass pilots including THE John Moore who wrote a hilarious (for the subject) Tailhook article, "Surviving the Cutlass." I think it was reprinted in his memoir The Wrong Stuff.

John said that after flying the X job he wrote General Electric:

"I have just flown Vought's XF7U-1 and thought you should know that your jet engines produce less heat than your toasters."

I believed him.
