MARINE CORPS AIRCRAFT
guidance for supporting arms including artillery, mortars,
naval surface fire support and close air support; and conduct
armed and visual reconnaissance.
The AH-1W is complemented with a night-targeting system that includes a FLIR, low-light TV, laser-designator/
rangefinder and an auto-track system. An embedded GPS/
inertial navigation system integrates the helicopter’s navigation and weapons system to provide accurate targeting to
the crew. Communication and navigation systems include
the ARC-210 radio that operates in fixed-frequency and
frequency-hopping anti-jam modes. The AH-1Ws currently
are being upgraded with a third-generation FLIR, Helmet
Display Tracking System and Tactical Video Data Link.
Since 2015, the AH-1W has been in the process of replacement by the AH-1Z.
Under the H- 1 Upgrades Program, the Marine Corps is providing increased operational capabilities through improvements
in crew survivability, payload, power available, endurance, range,
airspeed, maneuverability and supportability. The AH-1Z features
a new, four-bladed composite rotor system, performance-matched transmission, four-bladed tail rotor, upgraded landing gear and a fully integrated glass cockpit. The commonality
gained between the AH-1Z and the UH-1Y (about 85 percent) is
expected to reduce life-cycle costs and the aircraft’s logistical
footprint, while increasing maintainability and deployability.
The first low-rate initial production (LRIP) AH-1Z was
delivered in 2007. The Marine Corps will procure 189 AH-1Zs,
37 converted from AH-1Ws and 152 new build. Full-rate production of the AH-1Z was approved in 2010 and IOC was
achieved in February 2011.
Each of eight active and one Reserve Light Attack Helicopter
Squadrons (HMLAs) has a mix of 15 AH-1W/Zs and 12 UH-1Ys.
HMLA detachments routinely deploy onboard amphibious assault
ships with the Aviation Combat Element of a MEU, supporting
operations in Europe, Africa, the Middle East and the Pacific Rim.
AH-1s participated in combat operations since 2001 in Operations
Iraqi and Enduring Freedom. The AH-1Z first deployed in
October 2011 with a detachment from HMLA-367 (later transferred to HMLA-267) as part of the 11th MEU. HMLA-267 was
the first squadron to complete the initial transition to AH-1Zs.
As of October 2016, 107 AH-1Ws remain in the inventory
and 59 AH-1Zs have been delivered to the Marine Corps. The
AH-1Z has one Foreign Military Sale case with Pakistan and
other potential cases in work.

UH-1Y VENOM/HH-1N IROQUOIS
BRIEFING: The UH- 1’s primary tasks are to provide airborne
command and control for command elements; armed escort
for assault support operations; conduct combat-assault transport of troops, supplies and equipment; provide fire support
and security for forward and rear area forces; and provide terminal guidance for supporting arms, including CAS, artillery,
mortars and naval surface fire support.
The last UH-1N Iroquois (“Huey”) helicopters, which
entered Marine Corps service in 1971, were retired in
September 2014, having been replaced by the UH-1Y Venom.
The HH-1N Huey will remain in service until mid-2017 as a
utility and search-and-rescue (SAR) helicopter for air station
coverage at MCAS Yuma.
Under the H- 1 Upgrades Program, the Marine Corps is
providing increased crew and passenger survivability, payload,
power availability, endurance, range, airspeed, maneuverability and supportability. The Corps has remanufactured 10
HH-1N helicopters and is building 150 new UH-1Y models with
a four-bladed composite rotor system, performance-matched
transmission, four-bladed tail rotor, upgraded landing gear
and a fully integrated glass cockpit. The first low-rate initial
production UH-1Y was delivered in 2007.
Each of the nine active and one Reserve HMLA squadrons
eventually will have a mix of 15 AH-1W/Zs and 12 UH-1Ys.
HMLA detachments routinely deploy onboard amphibious
assault ships with the aviation combat element of a MEU, supporting operations worldwide.
The UH-1Y achieved IOC in August 2008. An HMLA-267
“Stinger” detachment joined Medium Helicopter Squadron
(HMM) 163 and took the UH-1Y on its first operational
deployment in January 2009. HMLA-367, the first full squadron to make the transition from the UH-1N, deployed to
Afghanistan in October 2009.
All six active-duty operational HMLA squadrons completed
transition to the UH-1Y by 2013, and the Reserve squadron in
mid-2014, bringing a closure to the UH-1N legacy fleet.
As of October 2016, the Marine Corps had taken delivery of
