The PC-1401 DSV (Deep Submersible Vehicle) is a civil submarine built at the traditional shipyard of
PERRY Submarine Builders, Florida. From the PC-series PERRY has delivered about 20 of specimen
The PC-14- subs belong to the medium size class of submarine crafts. Until 1986 the PC-1401 was operated
by the A&M University of Texas as "DIAPHUS" and solved about 300 dives in the Golf of Mexico.
Later it was located as "DEEP QUEST" on the Virgin Islands for various film and photo productions
and also took part on some movies (f.e. James Bond 007).
In the 90 ' it came back to PERRY and was used on trials of the fuel-cell developement.
Finally in 1994/95 it undergoes a complete refit and was modificated from a research sub to a
special salvage workboat on instruction of Mantz Unterwassertechnik.
Since then the PC-1401 succesfully operates in special recovery missions besides of localization
and survey diving.
