Nobody make a 1/48 scale kit, but Italeri made a 1/72 scale kit. Revell Germany later reboxed it with different decals. They're kinda hard to find, but I'm sure they're out there.
Both kits lack detail and have fit issues, and the italeri decals are inaccurate. They got the squadron designations wrong. The kit decals say HMM-464, which doesn't exist. However, there is an HMH-464, so a little surgery with an exacto knife can fix that. The main rotor head of both kits is down right sad. It's just too plain and basic. They could have done more, even for the small scale. The interiors and cockpits lack pretty bad too. They didn't make much of an effort to represent the cabin, and the cockpit doesn't even look like a 53 pit. Missile detectors which bulge out of the fuselage under the pilot/copilot escape hatches and before the folding tail section aren't even there. And neither is the Forward Looking Infra-Red (FLIR) ball.
Even with all of these problems these Italeri and Revell Germany kits are about the only kits out there of the CH-53E. Some patients, time, research and scratchbuilding could turn these kits into a good representation of the Marine Corp's "Big Iron." I only work on my CH-53E kit from time to time. I'm a 53E mechanic, so everything needs to be juuuust riiiiight.
