The Yankee Class Helo in Flight

01/22/2013: The video shows a UH-1 Y in operation at 29 Palms.

The Yankee class helo is an upgrade of the Huey. 

The Marines by upgrading both the Yankee and the Zulu gained some efficiencies useful for deployment operations.

As we argued earlier: “By adding, new combat capabilities, notably the V-22 and the F-35B, the ARG becomes a much more potent combat resource, and a welcome addition to CBG con-ops. In an age of diminishing physical assets – in this case ships – getting more punch for the buck is a key consideration. The tactical contribution is the ARG becomes part of a scalable response with respect to any evolving flash point crisis.

Like everything in life the cliché “the Devil is in the details” must be addressed. There good news because of another significant aspect of the USN-USMC modernization approach.  The ability to make better use of Amphib deck and below deck space is significantly enhanced by the new systems.Having the two modernized helos – the Zulu and Yankee Class – use the SAME engines means that support for two different engines aboard the ship is no longer necessary.  This frees up both manpower and maintenance space aboard the ship.”

For a good comparison of the Yankee and the Zulu see the following:

The UH-1Y variant modernizes the UH-1 design. Its most noticeable upgrade, as compared to previous variants, is a four-bladed, all-composite rotor system designed to withstand ballistics up to 23 mm. A 21-inch (530 mm) insert just forward of the main door has been installed for more capacity. The UH-1Y has upgraded engines and transmission, 170% increased payload over UH-1N, almost 50% greater range and maximum speed, a digital cockpit with flat panel multifunctional displays, and an 84% parts commonality with the AH-1Z.

On 8 August 2008, the Marine Corps certified the UH-1Y as operationally capable and was deployed for the first time in January 2009 as part of the aviation combat element of the 13th Marine Expeditionary Unit. The Marine Corps plans to eventually buy 123 of the Y-model Hueys to replace their inventory of N-models, with delivery of all aircraft to be complete by 2016.

The AH-1Z Viper

The AH-1Z incorporates new rotor technology with upgraded military avionics, weapons systems, and electro-optical sensors in an integrated weapons platform. It has improved survivability and can find targets at longer ranges and attack them with precision weapons.

An AH-1Z at an air show displaying four-blade rotors and longer stub wings.The AH-1Z’s new bearingless, hingeless rotor system has 75% fewer parts than that of four-bladed articulated systems. The blades are made of composites, which have an increased ballistic survivability, and there is a semiautomatic folding system for stowage aboard Amphibious assault ships. Its two redesigned wing stubs are longer, with each adding a wing-tip station for a missile such as the AIM-9 Sidewinder. Each wing has two other stations for 2.75-inch (70 mm) Hydra 70 rocket pods, or AGM-114 Hellfire quad missile launchers. The Longbow radar can also be mounted on a wing tip station.

The Z-model’s integrated avionics system (IAS) has been developed by Northrop Grumman. The system include two mission computers and an automatic flight control system. Each crew station has two 8×6-inch multifunction liquid crystal displays (LCD) and one 4.2×4.2-inch dual function LCD display. The communications suite combines a US Navy RT-1824 integrated radio, UHF/VHF, COMSEC and modem in a single unit. The navigation suite includes an embedded GPS inertial navigation system (EGI), a digital map system and a low-airspeed air data subsystem, which allows weapons delivery when hovering.

The crew are equipped with the Thales “Top Owl” helmet-mounted sight and display system. The Top Owl has a 24-hour day/night capability and a binocular display with a 40° field of view. Its visor projection provides forward looking infrared (FLIR) or video imagery. The AH-1Z has survivability equipment including the Hover Infared Suppression System (HIRSS) to cover engine exhausts, countermeasure dispensers, radar warning, incoming/on-way missile warning and on-fuselage laserspot warning systems.

The Lockheed Martin target sight system (TSS) incorporates a third-generation FLIR sensor. The TSS provides target sighting in day, night or adverse weather conditions. The system has various view modes and can track with FLIR or by TV.
