Robotech Defense Force

The Sivorsky 303 Sea Sergeant ASW Helicopter was a cargo transport of the Robotech Defense Force.

DevelopmentEdit

The Navy of the Robotech Defense Force prior to the First Robotech War was equipped with much the same hardware as their national ancestors and contemporaries, as the use of 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 UNDF to function effectively. Hence the material used by the UN Army and Navy groups was always top-quality, and thus better than most likely opponents, such as the Anti-Unification League.

Technology and Combat CharacteristicsEdit

The standard large shipboard helicopter, used for all kinds of work ranging from search and rescue to sub-hunting was the European Helicopters/Sivorsky Sea Sergeant. With a hull form reminiscent of the venerable Sea King and an advanced version of the systems used in the EH 101 this helicopter was the unchallenged winner of the navy competition for such an helicopter. Sea Sergeants could be found on most ships 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 off the coast of Macross Island for several submerged alien contacts, with tragic results for the crews.

ArmorEdit

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

HistoryEdit

Used extensively before and after the Zentraedi Holocaust, the design was later adopted by the Southern Cross Navy, which continued to use it (with regular electronic and engine updates) until it was mothballed for more modern designs. Examples of the helicopter however, or of its land-based Cargo Sergeant transport variant, could still be found in human resistance and other groups during and after the Invid occupation.
