This is a Sikorsky MH-53 Pave Low in Minecraft. This only took about 2 hours. The Sikorsky MH-53 Pave Low series is a long-range combat search and rescue (CSAR) helicopter for the United States Air Force. The series was upgraded from the HH-53B/C, variants of the Sikorsky CH-53 Sea Stallion. The HH-53 "Super Jolly Green Giant" was initially developed to replace the HH-3 "Jolly Green Giant". The helicopters later transitioned to Special Operations missions. The U.S. Air Force's MH-53J/M fleet was retired in September 2008 and was replaced by the CV-22B Osprey. 
The US Air Force ordered HH-53B and HH-53C variants for Search and Rescue units, and developed the MH-53J Pave Low version for Special Operations missions.
The Pave Low's mission was low-level, long-range, undetected penetration into denied areas, day or night, in adverse weather, for infiltration, exfiltration and resupply of special operations forces. Pave Lows often work in conjunction with MC-130H Combat Talon for navigation, communications and combat support,^[4] and with MC-130P Combat Shadow for in-flight refueling.^[5][6]
The large green airframe of the HH-53B earned it the nickname "Super Jolly Green Giant". This name is a reference to the smaller HH-3E "Jolly Green Giant", a stretched variant of the H-3 Sea King, used in the Vietnam War for combat search-and-rescue (CSAR) operations.
The US Air Force regarded their Sikorsky S-61R/HH-3E "Jolly Green Giant" long-range combat search and rescue (CSAR) helicopters favorably and was interested in the more capable S-65/CH-53A. In 1966, the USAF awarded a contract to Sikorsky for development of a CSAR variant of the CH-53A.
The HH-53B, as it was designated, featured:

• A retractable in-flight refueling probe on the right side of the nose.
  
• Spindle-shaped jettisonable external tanks with a capacity of 650 US gallons (2,461 L), fitted to the sponsons and braced by struts attached to the fuselage.
  
• A rescue hoist above the right passenger door, capable of deploying a Forest penetrator on 250 feet (76 m) of steel cable.
  
• Armament of three pintle-mounted General Electric GAU-2/A 7.62 mm (.308 in) six-barreled Gatling-type machine guns, with one in a forward hatch on each side of the fuselage and one mounted on the tail ramp, with the gunner secured with a harness.
  
• A total of 1,200 pounds (540 kg) of armor.
  
• A Doppler navigation radar in the forward belly.
  
  

Early HH-53Bs featured T64-GE-3 turboshafts with 3,080 shaft horsepower (2,297 kW) each, but these engines were later upgraded to T64-GE-7 turboshafts with 3,925 shaft horsepower (2,927 kW). Five crew were standard, including a pilot, copilot, crew chief, and two pararescuemen.
