The upper transducer in the bow is for BQS-2, the lower, for BQR-2, with a UQC-1 underwater telephone transducer in the fore end of the big sonar dome, and a UQN-1B (sounder) transducer in its bottom. The big tube under the nest of six bow tubes is the ejector pump (like the tubes, it had a shutter in the bow). |
Note that, unlike a fleet boat, Darter had a single engine room abaft her crew spaces, containing three engines side by side (types 2A & 6, the latter carrying the ST range only radar); a fixed whip (starboard side); the SS 2A radar mast (port); the UHF-IFF antenna; the retractable whip (port); the ECM/DF antenna (port) with a VLF loop (starboard) alongside; and the snorkel induction and exhaust.
Darter introduced the type of snorkel mast used in all later U.S. subs).
As in contemporary submarines, the ECM mast carries a series of stub dipoles along its length, with the dome of the direction-finder at the top. There was also a UQC-1 transducer on top of the sail, roughly alongside the UHF-IFF mast.
The line of masts divides the space below the sail into a control room to port and an attack center to starboard, with separate radio room abaft the control room and sonar room abaft the attack center.
Unlike a WW II sub (or a Tang class (SS-563/68)), Darter had her plane controls athwart-ships, on the forward bulkhead of the control room, alongside the helm. The six main controls, automatic depth control and UQC were all against the side of the pressure hull.

|276k||Mk 37 Mod 2 torpedo of the type carried by the Darter (SS-576), and other submarines during the Cold War. A 19 inch diameter weapon powered by batteries, it swam out of the tube instead of the traditional impulse shot, making it hard for the enemy to detect.|
Early versions of this torpedo were notoriously finicky. An overheating battery that lead to an explosion is one of the leading theories of the loss of the Scorpion (SSN-589).
During the 80's, the Darter normally carried two of these weapons in her after torpedo room, although up to four could be carried if two were tube loaded. Carried as a supplement to the normal load-out of Mk 48's in the forward torpedo room, they were mostly intended to be shot at pursuers during an evasion.
The Darter had the honor of shooting the last Mk 37 exercise rounds during a Tactical Readiness Evaluation at Pearl Harbor in June, 1985. In early 1987 she offloaded the last operational Mk 37 warshots, sending them to storage.
This particular weapon is part of the Lexington (CVT-16) museum at Corpus Christi, Texas.
