That is a question that greatly interests me as I'm keeping an eye on the replacement program for the CH-53K. It's very difficult to come up with an exact cost for an aircraft as so many other factors are in play. -Developments, updates, various different electronics, R&D costs and so on.
Including all costs, the CH 53 K , latest development of the Sea Stallion for the USMC, is predicted to cost $125 million per aircraft, plus $20,000 an hour operating costs !
The "flyaway" cost of each King Stallion is stated as much lower ($91 million USD per helicopter), but still higher than the V-22 Osprey tiltrotor, which is, however, a smaller capacity aircraft.

it cost around £8.950 for all the sea wall with barriers!
Primarily the large ones do, like the CH53 Sea-stallion and the CH47 Chinook. Those are large cargo choppers and they can taxi on the ground if they need to. Most of the smaller birds just have skids so they can just land and take off.

All US helicopters are advanced modernized versions (or descendents) of the Vietnam War era choppers: 1. CH-53 Sea Stallion (CH=Cargo helicopter) 2. AH-1 Cobra (AH=Attack Helicopter) 3. UH-1 Iroquois (the Huey/UH=Utility Helicopter) 4. HH Jolly Green Giants (HH=Heavy left Helicopter) 5. OH-58 Kiowa (Observation Helicopter/jet ranger) 6. OH-6 Cayuse (Observation Helicopter/this bird actually was designed to replace the US Army's O-1 Bird Dog artillery observation airplane; used for the last time in Vietnam).
