A U.S. Navy SH-60 Sea Hawk helicopter prepares to lift off from the flight deck of an Arleigh Burke-class destroyer. A helicopter deck (or helo deck) is a helicopter pad on the deck of a ship, usually located on the stern and always clear of obstacles that would prove hazardous to a helicopter landing.
The AW101 follows a conventional design layout, but makes use of advanced technologies, such as the design of the rotor blades, avionics systems, and extensive use of composite materials. [38] The fuselage structure is modular and comprises an aluminium–lithium alloy , designed to be both light and damage-resistant. [ 39 ]
In 1996, the USMC launched the H-1 upgrade program by signing a contract with Bell Helicopter for upgrading 180 AH-1Ws into AH-1Zs and upgrading 100 UH-1Ns into UH-1Ys. [6] [8] The H-1 program created completely modernized attack and utility helicopters with considerable design commonality to reduce operating costs. The AH-1Z and UH-1Y share a ...

Marine Industrial Design and Babcock NZ made the necessary structural changes. The RHIB was able to be relocated as a result of the innovative design of the new accommodation ladders which can stow compactly inside the ship (5 m × 2.5 × 2.5 m), rather than being externally stored alongside the ship as before. Improved design of the ladders ...
HNLMS Rotterdam was the result of a joint project between the Netherlands and Spain, which resulted in the Enforcer design. The ship is equipped with a large helicopter deck for helicopter operations and a dock for large landing craft.

Reduced noise is the main advantage of the configuration; some of the loud "spanking" sound associated with conventional helicopters arises from interaction between the airflows from the main and tail rotors, which in some designs can be severe. Also, helicopters using coaxial rotors tend to be more compact (with a smaller footprint on the ...
