Jodie Peeler is my go-to person for the Sikorsky SH-3 (H-3) Sea King. She graciously volunteered to be the guest blogger for this post, distilling the information that she's collected over the past two and a half decades on one notable H-3 assignment:
The Sikorsky SH-3 Sea King as Recovery Helicopter by Jodie Peeler
From Scott Carpenter's Mercury mission in May 1962 to the end of the
Apollo lunar program in December 1972, every NASA spacecraft crew
retrieved by helicopter was recovered by a Sikorsky Sea King (1). The
big, twin-turbine Sea King offered additional interior space, more
power, more safety and more versatility than the HUS-1s that recovered
Alan Shepard and Gus Grissom after their Mercury flights.
Besides, it was natural that the Sea King be pressed into service as a
recovery helicopter.
Throughout most of NASA's "expendable era," the
prime recovery ships were typically anti-submarine warfare carriers
(CVS), with Sea King squadrons already part of their air group. Sending
a CVS allowed the Navy to provide NASA a large, capable recovery ship
without diverting a scarce "big deck." (2) Although an LPH might be
pressed into service with an HS detachment aboard for some missions (3),
the CVS became the classic recovery ship, immortalized in countless
pictures, film clips, and even model kits.
One particular SH-3
itself became an icon. In particular, an SH-3D with the Bureau Number
152711 became a celebrity for its recovery of the first five Apollo
flights to the Moon. You may not know the number 152711, but chances are
you've seen pictures of "Old 66," a helicopter so famous it even inspired a love
song. (4)
Over the years the saga of "Old 66" has been told time and again, and a
certain mythology has built up - as have some misconceptions. What
follows is my attempt to assemble some things I've learned, based on
what I've found in readings and research.
THE RECOVERY OPERATION
For an Apollo recovery mission, a prime recovery ship embarked eight
SH-3A or SH-3D aircraft and associated personnel from the squadron. This
provided plenty of aircraft for the recovery mission, as well as spare
aircraft in the event one or more had an issue. The aircraft were
maintained in excellent condition and logged many hours in simulation
exercises (SIMEX) prior to splashdown day.
On a typical recovery, four helicopters participated, with one remaining
aboard ship ready to go if needed. Each had a four-person aircrew, plus
additional personnel as indicated. This is the deployment for Apollo 11
in July 1969:
- RECOVERY ONE: The prime recovery helicopter, responsible for picking
up the astronauts and bringing them back aboard the ship. RECOVERY also
carried a NASA flight surgeon, who would make initial assessments of the
astronauts once they were aboard; RECOVERY also carried the leader of
the Underwater Demolition Team to the recovery site. On flights that
observed quarantine protocol, RECOVERY also carried the Biological Isolation Garments (BIGs) and decontamination equipment to the
splashdown site.
- SWIM ONE and SWIM TWO: Each carried three Underwater Demolition Team
swimmers to the recovery site. These swimmers would secure the
spacecraft and assist the astronauts during recovery, then stay with the
spacecraft until it was retrieved. On Apollo 11, SWIM TWO deployed its
swimmers, while SWIM ONE hovered nearby with its swimmers as a waiting
backup. After the astronauts were aboard RECOVERY, SWIM ONE flew wing
with RECOVERY back to the recovery ship as a precaution, while SWIM TWO
"babysat" the spacecraft and swimmers until the PRS arrived. (5)
- PHOTO ONE: Carried two cameramen to capture still and motion picture
images of the recovery operation. Live television capability became
possible starting with Apollo 13 in April 1970. (6)
- In addition, SWIM THREE, with a crew of four plus a UDT swimmer, stood
by aboard the recovery ship ready to go if needed.
- Recovery ships with fixed-wing capability also launched two Grumman E-1
Tracers, one to serve as on-scene commander (call sign AIR BOSS) while
another (call sign RELAY) relayed on-scene communications back to the
task force headquarters in Hawaii. (7)
MODIFICATIONS TO RECOVERY HELICOPTERS
In spite of what has been written elsewhere, none of the SH-3s used by
HS units for spacecraft recovery were purpose-built rescue helicopters.
They were on temporary duty from their normal ASW/SAR mission, and none
of the aircraft were specialized rescue aircraft. (This changed starting
with Apollo 15, when recovery duty became the task of HC-1 and its
SH-3Gs.) (8)
Instead, temporary modifications were made to the SH-3A/SH-3D aircraft
used in recovery operations. It became typical to remove the AN/AQS-13
sonar equipment in most of the embarked helicopters and cover the top of the sonar well. (9)
This opened up space in the cabin for crewmembers to move around, room
for recovery gear, and to provide space for the astronauts and the NASA
physician to move around aboard the recovery helicopter.
Removing the sonar also made room for the SARAH (Search and Rescue and
Homing) equipment. This system provided a radio-detection system for
locating the spacecraft. It used Yagi-type antennas mounted at the top
of the port and starboard sponson struts; the first recovery helicopter
to sport these antenna was the Gemini 12 recovery helicopter in November
1966. The signals were fed to receivers in the helicopter's cabin, and
crewmen could use the signals to direct the pilots toward the
spacecraft's location. (10)
Not every aircraft embarked aboard a recovery ship would be modified. Of
the eight SH-3Ds embarked aboard USS Yorktown for the Apollo 8 recovery
in 1968, six aircraft had their sonar equipment removed, and five of
those had SARAH equipment installed. These modifications were performed
aboard ship by squadron personnel, using parts supplied to the squadron.
(11)
Starting with Apollo 10, the recovery helicopter was equipped with an
uprighting sling made of half-inch nylon line. One end of the sling was
attached to a weapons shackle; the other end was taped in place below
the starboard cabin door. If the command module was apex-down (Stable
II) after splashdown, a helicopter crewman could lower the free end of
the sling to a swimmer in the water, who would attach the sling to the
spacecraft. The helicopter could then pull the spacecraft over to
upright (Stable I) position. (12)
Other modifications to the prime recovery helicopter included installation of photo and film cameras on the starboard side. Two 70mm
motion picture cameras and a 35mm still camera were carried on a
specially-made mount on the starboard aft weapons position, and at least
one camera was mounted on the starboard side between the sponson and the
fuselage that was used to take this picture of Apollo 13 Astronaut Jack Swigert.
These cameras were pointed down to capture images of the
recovery operation that could be analyzed after the mission. These
supplemented the still photos and motion pictures captured by the PHOTO
helicopter.
The cameras mounted on recovery helicopters had no capability to
transmit live television pictures. Television audiences were limited to
what the cameras aboard the recovery ship could see. Live television
direct from the recovery scene did not happen until Apollo 13 in 1970,
when a live television relay from the PHOTO helicopter finally became a
reality. (13)
THE HISTORY OF BUNO 152711, "OLD 66"
Bureau Number 152711 (Sikorsky serial number 61-377) was constructed as an SH-3D
and completed on March 4, 1967. It appears to have spent its entire
career with the "Black Knights" of HS-4.
At this point I have not found out why 152711 was selected as prime
recovery helicopter for Apollo 8; perhaps it was the aircraft in best condition, the squadron CO's preferred aircraft, that its side number—66—had a certain something, or just luck of the draw. Regardless,
it was 152711 that brought the astronauts aboard Yorktown on
December 27, 1968, as live television from the recovery ship presented
the historic moment to a worldwide audience.
As it happened, 152711 was also used for the Apollo 10, 11, 12, and 13 recoveries. By late 1969, even though it had received a different, three-digit side number, for the Apollo 12 mission that was painted out and replaced with "66"!
For a online gallery of pictures from the Apollo 11 recovery at the USS Hornet Museum web site, see
http://usshornetmuseum.org/PhotoGallery/gallery.php?galleryFolder=1969_CVS_12_Apollo_11
The USS Hornet Museum staff has also posted a gallery for the Apollo 12 recovery:
http://usshornetmuseum.org/PhotoGallery/gallery.php?galleryFolder=1969_CVS_12_Apollo_12
Although 152711 was repainted and renumbered a few times after its last spacecraft recovery mission, it always bore five Apollo spacecraft symbols on both sides of the nose.
Old 66 was reportedly slated to be presented to the Smithsonian Institution when after it was no longer needed by the Navy. Unfortunately, it did not survive to be so honored for its prominent role in the Apollo program. On 4 June 1975, during a night training mission using its dipping sonar, 152711 crashed into the ocean off NALF Imperial Beach, California and sank. All four crewmen were rescued although the pilot subsequently died of his injuries.
At the time of the accident, 152711 had logged 3,245.2 flight hours and flown from at least seven aircraft carriers and helicopter landing craft. Although there has been interest in locating and raising it for restoration, the effort and expense of doing so from 800 fathoms deep have so far been prohibitive.
At least three SH-3s now on display have been repainted to resemble "Old 66". Two of these aircraft, BuNo 148999 aboard
Hornet (
http://www.uss-hornet.org/) and BuNo 149006 in the Evergreen Aviation Museum(
http://evergreenmuseum.org/), are themselves actual recovery helicopters, Gemini 4 and 7 respectively. (148999 was repainted for the 1995 motion picture Apollo 13.) The third is BuNo 149711 aboard
Midway in San Diego.
Notes:
1. Several spaceflights ended with the astronauts coming aboard the
recovery ship by means other than helicopter. This includes Mercury 6,
Mercury 8, Mercury 9, Gemini 6A, Gemini 8, Gemini 9, all three Skylab
missions, and the Apollo-Soyuz Test Project. This was sometimes due to
the spacecraft being retrieved by a smaller backup recovery ship; other
times, it was because the spacecraft landed close enough to the carrier.
The long duration of the Skylab missions meant keeping the astronauts
aboard the spacecraft until it was aboard ship was a safer move.
2. One myth that will not die is that USS John F. Kennedy was to have
recovered Apollo 11 in order to honor the late President who sent us to
the Moon, but that President Nixon vetoed this plan for political
reasons. In reality, diverting JFK from the Atlantic Fleet to the
Pacific just for the recovery mission would have been a logistical and
operational nightmare, impractical for many reasons. Correspondence
between CNO Thomas Moorer and NASA Administrator George Mueller details
that a CVS was chosen over an LPH because the CVS was a more prestigious
ship for such a high-profile mission. Hornet herself was selected
because she was readily available; had been training for related
missions; was more capable than an LPH; and would not have diverted a
larger carrier from duty off Vietnam. The historical record more than
justifies Hornet's selection, as ship, crew and squadrons performed
magnificently on a challenging mission.
3. Missions recovered by an LPH included Gemini 10 (USS Guadalcanal,
with HS-3 detachment), Gemini 11 (USS Guam, with HS-3 detachment),
Apollo 9 (USS Guadalcanal, with HS-3 detachment), Apollo 10 (USS
Princeton, with HS-4 detachment), Apollo 13 (USS Iwo Jima, with HS-4
detachment), and Apollo 14 (USS New Orleans, with HS-6 detachment). In
addition, an HC-1 detachment with SH-3Gs was deployed aboard USS Okinawa
for Apollo 15, and aboard USS New Orleans for its three recoveries
during the Skylab and Apollo-Soyuz era. Gemini 8 would have been
retrieved by USS Boxer had the mission gone as planned.

5. Several accounts tell the story of how SWIM TWO got the call,
including Scott Carmichael's "Moon Men Return: USS Hornet and the
Recovery of the Apollo 11 Astronauts" (Naval Institute Press, 2011), p.
178-183. Live TV coverage of the Apollo 11 recovery also shows SWIM ONE
flying RECOVERY's wing on the way back to Hornet.

of the Apollo 11 Recovery" (Creative Minds Press, 2010), p. 107.
8. Al Adcock's "H-3 Sea King In Action" (Squadron/Signal Publications,
1995) implies that the SH-3s that recovered Apollo astronauts were
specialized SAR variants. However, multiple sources from the period
confirm the SH-3A and SH-3D aircraft from HS squadrons were
fully-capable sub hunters whose primary mission was antisubmarine
warfare. Had it not been, there would have been no need to remove the
dipping sonar from these aircraft; and had it not been, 152711 would
have not crashed during a night ASW training exercise in 1975.
9. Removal of the AN/AQS-13 equipment and installation of the SARAH
equipment is mentioned in the HS-4 summary from USS Yorktown's Apollo 8
post-recovery report, provided to the author by the Naval Historical Center.
10. The first mission with Yagi-equipped recovery helicopters was the
Gemini 12 recovery in November 1966, as can be seen in contemporary
photos and films of the recovery. Details on the SARAH installation
aboard the helicopters comes from Fish, p. 79-80.
