Two universal stations under each stub
wing can carry 2.75in (70mm) rockets in
7-tube LAU-68 or 19-tube LAU-61 launchers,
one AIM-9 Sidewinder air-to-air missile or
M299 Hell re missile launcher. The latter
con guration allows the AH-1Z to carry up
to 16 laser-guided AGM-114 missiles. Two

stations, located on the stub wing tips, can
carry AIM-9 missiles
The AH-1W’s turret system is retained
along with the M197 20mm cannon and 750
rounds of ammunition. Controllable from
either crew station, the turret is operated
in  xed, TSS/gun or HMS/D mode and the

cannon  res at a rate of up to 1,500 rounds
per minute.

TESTING AND PRODUCTION
Assembly of the AH-1Z prototypes began
in April 1999 and the initial Viper turned
its new four-blade rotor for the  rst time at
the contractor’s Flight Research Center in
Arlington, Texas, on September 6, 2000.
Zulu 1  ew for the  rst time in Arlington on
December 8 and, after  ying 59.9 hours,
shifted to NAS Patuxent River, Maryland in
April 2001.
Zulu 1 retained the AH-1W avionics and
was primarily tasked with envelope expansion,
handling qualities and structural  ight testing.
Although testing continued at Pax River with
the H-1 Upgrades Integrated Test Team,
issues were discovered and associated
design modi cations caused delays with  ight
testing. The third prototype  ew for the  rst
time at Pax River on August 26, 2002 and
was followed by the number two aircraft on
October 4.
Although it was primarily centred at the
Maryland base, testing was carried out at
other several other locations, including Naval
Air Weapons Station China Lake, California,
and the US Army Yuma Proving Ground in
Arizona.
The programme faced cancellation when
it was revealed in April 2002 that costs had
jumped almost 49% and would exceed its
$3.7bn budget by more than 15%. Following
a thorough review, the Department of Defense
allowed the project to proceed.
Initial sea trials were conducted aboard
the USS Bataan (LHD 5) in May 2005 and
development testing was completed in
February 2006.
Low-rate initial production began at Bell’s
Military Aircraft Assembly and Delivery Center
in Amarillo, Texas, in October 2003. Delivery
of the  rst production AH-1Z followed on
January 25, 2007 – two years later than
originally planned.
The programme originally included
remanufacturing 180 AH-1Ws to AH-1Z
con guration. However, in 2008 the decision
was made to build 58 new aircraft and
reduce the number of remanufactured aircraft
accordingly.
