GUPPY IA Program
BuShips devised the GUPPY IA (SCB 47A) program of 1951 as a cheaper alternative to the GUPPY II conversion. While the GUPPY IA conversion included most features of the GUPPY II, it omitted the four-cell battery configuration and extensive internal rearrangement associated with it. Instead, the GUPPY IA retained the original battery wells, fitted with more powerful Sargo II batteries. These batteries featured electrolyte agitation, battery cooling, and open tank ventilation. They also had a longer life than the Guppy batteries, though shorter than the original Sargo battery. The sonar room was relocated from the forward torpedo room to a space under the galley. Compared to the GUPPY II, the GUPPY IA offered lower cost, better habitability, and easier maintenance at the expense of underwater performance.

Famous quotes containing the words guppy and/or program:
“It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
—Shusha Guppy (b. 1938)
“Utah is the only State that gives condemned men a choice between death by hanging or before a firing squad. Most prisoners prefer the firing squad, but one obstinate convict in 1912 elected to be hanged because “hanging is more expensive to the state.””
—State of Utah, U.S. public relief program (1935-1943)
