    U.S. Army AH-64D Block III helicopter crews exercised directional control of the MQ-1C Grey Eagle unmanned aircraft system (UAS) during the recently completed initial operational test and evaluation (IOT&E) of the upgraded Apache. The Army will decide whether to approve full-rate production of the Block III in July, including production of the mast-mounted UAS tactical datalink assembly (UTA) developed to control the Grey Eagle. The Army plans to acquire 690 Apache Block IIIs, mostly remanufactured by Boeing from earlier versions.

    Apache Block IIs can receive streaming video from unmanned aircraft through the VUIT-2 (Video from UAS for Interoperability Teaming Level II) and follow-on MUMT-2 (Manned-UnManned Teaming-2) systems. The UTA is a two-way datalink that provides higher-tier Level 3 control of UAS sensors and weapons and Level 4 capability to redirect an unmanned aircraft to points of interest in flight. The system is contained in a doughnut-shaped, mast-mounted radome identical to the radome housing the current Longbow fire-control radar (FCR) and sharing 50 percent common components. It was developed by the Longbow llc joint venture of Lockheed Martin and Northrop Grumman. Future 24-aircraft battalions will have nine helicopters equipped with the FCS, nine with UTA and six with no mast assembly.

    The UTA is a Ku-band system that currently can communicate only with the General Atomics Grey Eagle, although it will be further developed to operate in multiple bands. In a briefing at the AAAA conference in Nashville, Tenn., earlier this month, Lt. Col. Dan Bailey, the Army’s Apache Block III product manager, said the RQ-7 Shadow is in development testing for Ku-band interoperability, and the RQ-5 Hunter is beingconsidered for the same capability. “We’re not sure that [smaller UAS] will ever move to this kind of capability, but we may not ever want to control them, as well,” Bailey said. “The Army is still feeling out that overall concept.”

    The IOT&E testing was conducted at the Army’s National Training Center at Fort Irwin, Calif. Five Apache Block IIIs participated, including two with the UTA, two with the FCR and one “vanilla” helicopter. The interoperability testing also involved five Block II Apaches, a Grey Eagle unit based at Edwards Air Force Base, Calif., and the so-called AB3 National Airspace Trainer, a manned OH-58 helicopter serving as a UAS surrogate.

    Senior Army officers said that Apache copilot gunners were easily able to control
    the UAS, but that tactics need to be fleshed out. “The performance of the system has been great [and] the aircrews’ interaction with it also was good,” said Col. Shane Openshaw, Apache project manager. “They went through a learning curve, because they’re learning how to apply tactics, techniques and procedures to the kit and work in a manned-unmanned teaming environment.”

    AN/APG-78 Longbow fire-control radar (United States), Airborne fire-control radars

    [​IMG]

    Type
    Millimetric fire-control radar.

    Description
    The AN/APG-78 radar forms part of the Longbow fire-and-forget anti-armour system that is fitted to AH-64D Apache battlefield attack helicopters. The radar subsystem comprises a low probability-of-intercept Ka-band (35 GHz centre frequency) radar mounted on top of the helicopter's main rotor mast and a millimetric radar for the Radio Frequency (RF) Hellfire missile. This latter item uses the weapon's standard bus. The Longbow radar is designed to interface with the AH-64's fire-control system and provides rapid target area search; automatic target detection, classification and prioritisation; fixed and moving target detection (at 'maximum stand-off range') and missile fire-and-forget capabilities within a 55 km2 area. As such, the radar is reported to have shown a 28-fold improvement in battlefield effectiveness over the non-radar AH-64A during US government operational tests. An integrated passive radar band interferometer subsystem (designated as the AN/APR-48A Radio Frequency Interferometer - RFI) is used to locate and identify radiating targets and to cue the AN/APG-78 radar, while the Longbow system as a whole identifies and ranks
    targets in priority order for attack by RF Hellfire missiles. Here, up to 16 of the highest priority targets can be displayed simultaneously, at ranges of up to 8 km for moving targets. In addition to its fire-control functions, AN/APG-78 is also noted as offering terrain profiling and air over-watch capabilities.

    This helicopter would be fine, But IAF had to procure more than 2000 Agm-114 hellfire missiles along with it. Definitely this going to give a shock to our Hostile Neighbour.

    These estimates about Z-10 might be wrong as nothing much is known of the chinese copter,
    but one thing is clear, Apache Block-III is definitely ahead of Z-10 or then any other attack helicopter in the world presently.
