SV-51
A transformable mecha from the [[MACROSS]] universe. 

In the [[macross zero|Macross Zero]] OVA the [b]Sukhoi/Israel Aircraft Industries/Dornier SV-51[/b] was the only [[variable fighter]] developed by the [[anti-u.n.|Anti-U.N.]] forces. It can transform into [[battroid]] (giant robot), [[GERWALK]] and fighter (jet) modes.

The [b]SV[/b] in its name actually stands for [b]"Sukhoi Variable"[/b] (or [b]"Slayer Valkyrie"[/b] according to some other sources).

Like the [[vf-0|VF-0]] Phoenix, the SV-51 is an advanced trial production model equipped with conventional engines, a proof-of-concept craft developed and pressed into service before planned variable fighters with thermonuclear turbine engines. It can only fly in an atmosphere and is not a [[space]] travel-capable aerospace fighter like the later [[vf-1|VF-1]]. A variant called [b]SV-52[/b] with thermonuclear reaction engines was also researched but wasn't mass produced by the Anti-U.N. forces.

The SV-51 armaments included gun pods, missiles, and other ordinance. The mecha was also capable of being launched from underwater. The fighter design was similar to that of the VF-0, but its transformation mechanism was more complicated and took longer to complete. The SV-51 also had [[canards]] and tailplanes. Its wing was narrow and relatively unswept.

Since this [[mecha]] appeared a whole year before the events of [[Choujikuu Yousai Macross]], many [i]Macross[/i] fans have speculated that the remaining units were seized by the [[U.N. Spacy]] and used for variable fighter research as well as aerial defense against the [[Zentradi]] during Space War I (like they did with the Anti-U.N. [[Octos]] mecha, according to the [i]Macross Chronicle[/i]). The SV-52 variant with reaction engines was also supposedly produced in limited numbers by the U.N. Spacy after the Anti-U.N. forces were defeated.

The SV-51 was designed in [[real life]] by [[kawamori shouji|Kawamori Shouji]].
