This weapon has been cancelled.

The tubes are much wider than the torpedoes allowing quieter
"swim-out" (rather than gas ejection) launch. The hull has an anechoic
coating also.

The flank arrays include the BQG-5 Wide Aperture Passive Ranging
Array (a descendant of PUFFS and MicroPUFFS). All of this stuff to be
knit together with the controversial and expensive BSY-2.

The fins are in an unusual pattern. The "normal" four set apart at 90
degree angles (N,S,E,W so to speak) and two more stuck in on the
bottom (SE and SW).
