27 February Airborne mine countermeasures began
off Haiphong during Operation Endsweep. This was a
"first" in mine warfare as airborne minesweeping had
never been done with "live" mines. A CH-53 Sea
Stallion from HM-12 made two sweeps in the Haiphong
shipping channel. All operations were abruptly halted
and minesweeping task force moved to sea as the
President called for "clarification. . . on a most urgent
basis" of Hanoi's delay in releasing American POWs.
4 March The withdrawal of U.S. troops from
Vietnam resumed and the naval mines weeping force
returned to its position off Haiphong. Minesweeping
operations continued in and around Haiphong and the
harbor was reopened after being closed for ten
months because of the U.S. naval mining which began
in May 1972. In addition, America was ordered to
depart the Far East for the U.S. This was the initial
move in reducing the number of carriers serving in
Southeast Asia from six to three by mid-June 1973.
21 March VXN-8 returned to NAS Patuxent River, Md.,
from Project Magnet deployment to the Southern
Hemisphere under the direction of the U.S. Naval
Oceanographic Office. During the deployment, two
flights were made around the world within the Southern
Hemisphere, and an over-the-South-Pole flight by an RP-
3D on 4 March was a first for that type of aircraft.
29 March The remaining U.S. combat forces left
South Vietnam; and the United States Military
Assistance Command, Vietnam (MACV), was disband-
ed, officially ending U.S. military involvement in South
Vietnam. The last phase of Operation Homecoming
was concluded when the final group of 148 American
POWs was released by Hanoi. This brought the total
to 591 POWs released, 566 of whom were U.S. military
personnel with 144 being naval pilots and aircrewmen.

final phase of the reorganization of the AirLant com-
munity, completing the functional wing concept: Air
Antisubmarine Wing One with VS-22, -24, -27, -30, -31
and -32 and Helicopter Antisubmarine Wing One with
HS-1, -3, -5, -7 and -11.
13 April The Secretary of the Navy announced that
an agreement with the United Kingdom had been
signed providing for an eight-month joint study of an
advanced V/STOL Harrier involving participation by
Rolls-Royce, Hawker-Siddeley, Pratt & Whitney Aircraft
and McDonnell Douglas. The overall aim was to deter-
mine the feasibility of joint development of an
advanced concept V/STOL incorporating a Pegasus 15
engine and an advanced wing.
16 April The Cruise Missile Project Office was estab-
lished in the Naval Air Systems Command with
responsibility to develop both tactical and strategic
versions of the cruise missile.

stabilized the situation.
8 May In a ceremony at the Douglas Aircraft Division,
Long Beach, Calif., the first McDonnell Douglas C-9B
Sky train jet transports were accepted by the Navy and
delivered to Fleet Tactical Support Squadrons One and
Thirty. A commercial version of the DC-9, the C-9B had
a maximum 32,444 pound payload range of 1,150
statute miles with a ferry range of about 3,400 miles. It
accommodated 107 passengers five-abreast.
18 May A four-day trial of a prototype glide slope
indicator was completed aboard Truxtun (CGN 35).
The indicator, developed by the Naval Air Engineering
Center, consisted of a hydraulically stabilized Fresnel
lens. It was one of several steps taken to achieve an
all weather capability with LAMPS helicopters.
