(SH-62 Sea Sergeant)

Four hardpoints on the wings typically each carry:Honeywell mk53 Kraken1

  • 1 x Honeywell mk53 Kraken or Marconi Underwater Systems Sting Ray mk2 ASW torpedoes,
  • or 1 x AGM-84F Harpoon anti-ship missile,
  • or 1 x Penguin anti-ship missile,
  • or 1 x ANS anti-ship missile,
  • or 1 x Derringer anti-surface missile,
  • or other alternative military loads such as fuel or cargo containers.

(Optional – All)

  • 1 or 2 x GAU-20A1 .50 BMG (12.7×99mm) belt fed, recoil operated machine gun. Rate of fire is 600 rounds per minute. Can fire the full range of .50BMG ammunition, to include M903 Saboted Light Armor Penetrator (SLAP). These machine guns, when used, are mounted in the left and/or right cargo doors. Typical combat load is 2000 rounds per gun.

VIII. Armor:

The skin of the Sea Sergeant is composed of treated magnesium plate. The skin provides fair protection against small arms fire, and good protection against small grenade and shell fragments, though it is especially vulnerable to incendiary weapons.

IX. Development:

The Navy of the pre-holocaust UN Spacy was equipped with much the same hardware as their national ancestors and contemporaries, as the use of expensive Robotechnology was at first limited to combat units more likely to engage the alien enemy, such as the orbital forces and the Veritech squadrons. However, this did not mean that these divisions were under-appreciated, as at least a semblance of internal peace was required for the United Nations of Earth Government (UNEG) to function effectively. Hence the material used by the UN Spacy’s earth bound units was always top-quality, and thus better than most likely opponents, such as the Anti-Unification League.

The standard large shipboard helicopter, used for all kinds of work ranging from search and rescue to sub-hunting was the Sikorsky SH-62 Sea Sergeant. With a hull form reminiscent of the venerable Sea King and an advanced version of the systems used in the AgustaWestland AW101 Merlin, this helicopter was the unchallenged winner of the UN Spacy competition for such a helicopter. Sea Sergeants could be found on most UN Spacy surface combatants and also on many land bases. Ironically, this design was the first Earth-side combat unit in contact with the invading Zentraedi, when two Sea Sergeant helicopters were dispatched to investigate several submerged alien contacts off the coast of Macross Island, with tragic results for the crews.

Used extensively before and after the Holocaust, the design was later adopted by the UEDF’s Navy, which continued to use it (with regular electronic and engine updates) until the Invid invasion. Examples of the helicopter, or of its land-based HH-62 Supply Sergeant transport variant, could still be found in human resistance and other groups during and after the Invid occupation.
