Named after the first Texan to set foot on Antarctica, during the 1938 Denton-Hellas Antarctic Expedition. The Muñoz is a sister ship to the RSAC Tir-Bauth, ordered within 2 years of each other. The Muñoz is stationed in Rhone, [[Denton]] and works with the TPRI Antarctic branch. The Muñoz is Texas' first Icebreaker.

Aircraft

Donnelley GH-3 Gyrodyne

The GH-3 Gyrodyne was first introduced in 1963, by Donnelley Aerospace of Tramore, Salide. The initial design has seen many upgrades through the years, the most prominent of which is the silencers added to the rotor tip-jets, which reduced the noise from 115db to 95db. The implementation of more powerful engines and two forward facing propellors driven by the main engines to create quick forward movement have made the GH-3 the most popular light helicopter in the United Antarctic Programme.

  • Crew: 1-2
  • Capacity: 7 passengers or 1000kg internally, 1200kg on external sling
  • Cruise Speed: 280kmh
  • Range: 600km
  • Hover Ceiling: 4200m

Worth U21P

The Worth U21 is a Texan mid-size helicopter, with a capability similar to that of a Bell 412 or Kamov 27. The base aircraft model was introduced in 1980, with a polar variant introduced in 1984. It is equipped with a co-axial rotor configuration and 4 wheel landing gear.

  • Crew: 2
  • Capacity: 16 passengers or 3500kg internally or 4000kg on external sling
  • Cruise Speed: 205kmh
  • Range: 1030km
  • Hover Ceiling: 5000m
