Here’s a significant reason why it’s more complex - because it’s required to do this to fit aboard ship:

It is an impressive machine, no doubt. One of the big problems they had early on IIRC was the hydraulic tubing that fed the engine nacelle units on the wings...the clamps for the pipes not only did not prevent vibration, they allowed sand and grit to enter the clamping structure, and would set up a hole to be worn through due to vibration and abrasion.
They had to redesign and replace all the tubing and clamps for the tubing so it would specifically not allow grit to enter.
