Why paint any markings at all if the hatches are welded shut?

USN's notion of weapon elevator marking visibility requirement constitute a sample of one as far as Weapon elevator visibility requirement goes. it is difficult to draw generalized conclusions from a sample of one. PLAN's notion of marking visibllity needs does not have to resemble those of the USN in all respects.

Like the Russians, the Chinese mark out the parking positions of aircrafts on deck, the USN AFAIK does not do that.

The Nimitz has anchors all over the deck and aircraft can be tied down almost anywhere. On the Kuznetsov class, those anchors are only placed around designated parking spots. Aircraft cannot be parked anywhere other than at those locations, hence the markings for parking positions. It is another limitation from Soviet design that PLAN will have to live with.

Perhaps when the crew starts weapon handling, PLAN will decide to add the hazard outlines again. Until then, this is the current version of deck markings.

By the way, counting all the marked spots on the deck they can park there without problems 24 fighters and few helos.

It seems unlikely that all 24 spots on deck would be simultaneously useable while flight operation occurs.

It appears the waist launch position is marked to launch aircraft over the bow, not over the front of the overhang. Launching them over the bow from waist position enables a longer takeoff roll and heavier take off weight. It may even allow a turboprop AWAC to take off unassisted.

Is that because the Su-33 and the Kamov helicopters are of similar size while the variation in size of USN aircraft is much wider?

no, and actually the opposite is true Delft.. the USNs primary carrier aircrafts are closer in dimensions than the Flanker/Kamov pairing

Flanker
Length: 21.94 m (72 ft)
Wingspan: 14.70 m (48.25 ft)
Height: 5.93 m (19.5 ft)

Kamov
Length: 12.5m
Rotor diameter: 2x 14.50 m (2x 47 ft 7 in)
Height: 5.6m

Super Hornet
Length: 60 ft 1¼ in (18.31 m)
Wingspan: 44 ft 8½ in (13.62 m)
Height: 16 ft (4.88 m)

Seahawk
Length: 64 ft 8 in (19.75 m)
Rotor diameter: 53 ft 8 in (16.35 m)
Height: 17 ft 2 in (5.2 m)

The main reason the US does it like this is so they an spot aircraft anywhere on the flight deck they want. During air launches, or recovery, clearly the aircraft will not be spotted and/or tied down in those areas. But during transits, various weather conditions, and other conditions, events, or exercises, the US Navy has the capability and the flexibility to spot the aircraft wherever they choose on that huge four and one-half acre (196,020 square feet) flight deck.

The distance between tie downs is gauged to allow for all of the different sizes of aircraft the US Navy uses, from the C-2s and E-2s, to the helos, the Hornets, Growlers, Prowlers, the eventual F-35s, Ospreys, and UAVs, etc.

Yes that is correct. As big as the hanger is om the nimitz class, it can't accomodate all the aircraft of the cvw. Some has to be tied down on deck especially during high sea states.

You want to make it VERY VISIBLE so that some poor sailor is not accidentally standing on top of it or park a vehicle/plane etc over it when some poor sap wants to bring some missiles or bombs up to the flight deck!

So true..When I was aboard the JFK we had a young man..fresh outta boot camp ..fall down an lower stage elevator shaft.. from the 2nd to the 7th deck. He was DOA. Not something I want to ever see again.

Why paint any markings at all if the hatches are welded shut?.. PLAN's notion of marking visibllity needs does not have to resemble those of the USN in all respects.

True Chuck, no need to paint the hatch if it is welded shut... but if it is not, it is a matter of safety and tried, true and proven methods of operations for the last 92 years.
