Partial data submitted by Ron Reeves (of blessed memory)

As built to the specifications: Displacement, Surfaced: 1,570 t., Submerged: 2,414 t.; Length 311' 8"; Beam 27' 4"; Draft 15' 3"; Speed, Surfaced 20.25 kts, Submerged 8.75 kts; Cruising Range, 11,000 miles surfaced at 10kts; Submerged Endurance, 48 hours at 2kts; Operating Depth, 400 ft; Complement 7 Officers 69 Enlisted; Armament, ten 21" torpedo tubes, six forward, four aft, 24 torpedoes, one 5"/25 deck gun, two 20mm guns, two .30 cal. machine guns; Patrol Endurance 75 days;
Propulsion, FOUR "slow speed" main motors, two wound directly on a hollow, forged steel shaft that flanged up with its respective propeller shaft. There were NO reduction gears connecting the main motors to the propellor shafts. These were Elliot "double armature" motors, i.e. there were two separate 1350HP motors contained in each motor housing that were mechanically wound on one shaft. Each of the 4 motors could be electrically operated independently from the other three. Each of the two main motor housings contained cooling water and cooling air systems to service the motors.
Also, the Guppy III conversion gave Volador four Gould TPX-67A - 126-cell batteries for a total of 504 cells contained in three battery wells. The third, smaller ("annex well") was located in the 15' hull section at the forward end of Control that was added during the Guppy III conversion. Fuel Capacity, 113,510 gal., two propellers.

Volador 82k ASROC torpedo sticking out of Volador's (SS-490) sail while the boat was a Guppy II. Photo circa 1961.

By 1960, the US Navy was developing the MK44 rocket-thrown antisubmarine torpedo system, known as ASROC for Anti-Submarine Rocket. As part of the test program, King (DLG-10) and other ships had launcher systems installed and would soon give the weapons system a crucial test.
Because ASROC and another US destroyer torpedo-delivery program, DASH - for Drone Anti-Submarine Helicopter, were intended to employ torpedoes that could have nuclear warheads, it was also necessary to develop long range active SONAR systems that would permit anti-submarine task forces to stand off a safe distance from their intended targets. These included the AN/SQS-23B and AN/SQS 26 sonar systems.
Thus, the stage is set for multi-billion dollar, comprehensive multiple weapons systems developments intended to equip the US Navy to effectively counter the growing Soviet submarine threat.
In August 1960, King was assigned the services of a "target" submarine, Volador, then a Guppy II diesel boat operating out of San Diego for the purpose of testing the new ASROC MK-44 torpedo system. With the submarine at periscope depth, being tracked by King's SQS-23B sonar, King fired an ASROC.
Incredibly, the MK-44 torpedo separated from the rocket motor at the appropriate point and then punched through the thin skin of Volador's superstructure "sail" within a couple seconds of its entering the water. Other than requiring the services of a laundry, however, the only other damage done to Volador was a hole in its sail.
In fact, the Chief of the Boat ("COB") Darryl Bailey STC(SS) reminded me during a Volador reunion in June, 2004, that Volador was scheduled to serve as "visit ship" at Broadway Pier that very weekend. In order to keep that commitment, COB Bailey had the topside gang tape a piece of newspaper over the hole caused by the MK-44 torpedo and then repaint the area. His ploy worked, not one single visitor noticed the hole in the sail.
The point is that had the ASROC shot been for real, it would not have been a "kill" because the MK-44 torpedo struck Volador's sail immediately after entering the calm waters of the Pacific Ocean. It did not start, let alone complete its "enabling run" prior to lodging itself in Volador's sail area. Experience gained during wartime had taught the Navy to have a newly launched torpedo complete a short run before its warhead became fully armed - or "enabled." So this particular shot was a "dud" because King's fire control party had failed to enter the mandatory enabling run prior to firing their ASROC.
The Navy, Norfolk Naval Shipyard, in particular, however, used the photos shot by SUBMARINE FLOTILLA ONE's photographer and incorporated them into a report as graphic testimony to the effectiveness of the ASROC weapons system! No mention was ever made of the firing solution error committed by the fire control party aboard King.The next encounter in the summer of 1961 saw Volador again providing target services to King for yet another ASROC systems test. This was to be the "qualification test" in which King would earn its credentials to carry - and employ - ASROCs in attacks on a hostile submarine.
Volador was at periscope depth, rigged for collision. The Commanding Officer, LCDR H. Ray Heimback, USN, announced over Volador's 1MC as each critical point in King "attack" was reached. Finally, he announced "The torpedo is in the water!"
Several seconds later, we felt a boat-jarring WHUMP!!! - King's torpedo had struck our after marker buoy fairing, leaving a sizable dent. That dent was still visible when I reported back aboard Volador in 1964 as an officer, but virtually none of that present crew had the slightest idea what had caused it. But King's crew had learned its lesson - had that been a war-shot, we would have been dead! 		Photo & text courtesy of Bill Parker LT, (USN Ret).

This picture was taken sometime after January, 1964. At that time the Baya had emerged from a conversion that gave her the configuration that is shown here. This also correlates to the Guppy III in the background, the Volador. She was converted to this configuration in 1963. The rest of the boats have what is called the "Queenfish Mod", a minimal attempt at streamlining by removing all the deck guns and topside ammo lockers and cutting away small portions of the fairwater.
