The landing craft, vehicle, personnel (LCVP) or Higgins boat was a landing craft used extensively by the Allied forces in amphibious landings in World War II.Typically constructed from plywood, this shallow-draft, barge-like boat could ferry a roughly platoon-sized complement of 36 men to shore at 12 knots (14 mph; 22 km/h).
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail. [ 1 ] [ 2 ] The term taildragger is also used.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The Junkers Ju 87, popularly known as the "Stuka", [b] is a German dive bomber and ground-attack aircraft.Designed by Hermann Pohlmann, it first flew in 1935.The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War of 1936–1939 and served the Axis in World War II from beginning to end (1939–1945).
The main landing gear, housed in the nacelles behind the engines, were raised and lowered hydraulically. The main landing gear shock absorbers were de Havilland manufactured and used a system of rubber in compression, rather than hydraulic oleos, with twin pneumatic brakes for each wheel. [ 107 ]

The Junkers Ju 287 was a multi-engine tactical jet bomber built in Nazi Germany in 1944. It featured a novel forward-swept wing, and the first two prototypes (which were aerodynamic testbeds for the production Ju 287) were among the very few jet propelled aircraft ever built with fixed landing gear.
It was also used for liaison and transport duties and short-range reconnaissance which required airplanes to land and take off in short distances from unprepared landing strips. Liaison pilots would train on L-3s before moving on to front-line aircraft like the Piper L-4 or the Stinson L-5 .
