    Ten different ways to kill a carrier

    1. Megaton-class EMP (electromagnetic pulse) via DF-5 ICBM five megaton warhead or DF-3A IRBM with 3.3 megaton warhead

    2. Conventional-powered EMP with limited range

    3. DF-21D anti-ship ballistic missile (ASBM)
    a. high explosive
    b. flechettes
    c. cluster bombs

    4. WU-14 hypersonic glide vehicle (HGV) at prototype stage

    5. CM-400AKG Wrecker air-to-surface missile with terminal hypersonic steep dive and powered by a solid-rocket motor

    6. Luoyang/CASC LS-6 guided glide bomb with 60km range

    7. C-803 anti-ship missile with a supersonic terminal phase

    8. Stealth cruise missile (like the AGM-129 ACM)

    9. Yu-6 (Mark 48 class) heavyweight torpedo

    10. EM-66 torpedo-shaped self-propelled mine

    Today, I want to discuss the Chinese Luoyang/CASC LS-6 glide bomb with 60km range. If you send out a squadron of J-20 stealth fighters and/or Lijian stealth UAVs with LS-6 glide bombs (or possibly classified stealth glide bombs), it would be a standoff simultaneous attack that would be extremely difficult to defend against.

    Luoyang/CASC LS-6 Satellite Aided Inertially Guided Bomb Family

    The LS-6 designation is applied to a family of guidance kits for a range of low drag bomb bodies. Known variants of the tailkit are for 500 kg, 250 kg, 100 kg and 50 kg bombs. The former variants are glidebombs, the latter variants strake equipped analogues to the US GBU-39/B Small Diameter Bomb (SDB).

    The 500 kg / 250 kg LS-6 glidebomb design is modelled in many respects on the concept of the Australian developed planar wing Kerkanya glidebomb kit, more recently adapted to form the JDAM-ER. Unlike the Kerkanya which uses a low wing monoplane configuration with a blended adaptor fairing, the LS-6 glide wing kit is much simpler in design and the weapon flight configuration is that of a high wing monoplane. Cited range for an 11 km release altitude at 900 km/h is 60 km, considerably less than the Kerkanya/JDAM-ER design[4].

    In 2010 Luoyang displayed 100 kg and 50 kg derivative designs, which are clearly intended to be analogues to the US GBU-39/B Small Diameter Bomb (SDB) which has developed to fit the weapon bays of the F-22A Raptor[3].

    These weapons are clearly designed for compact internal carriage, and it is reasonable to conclude that the intended launch platform is the J-20 stealth fighter.

    Both the 100 kg and 50 kg derivatives are fitted with nose mounted electro-optical seekers, with high quality planar windows. JDW's Hewson reports this to be a semi-active homing laser seeker, however, such a seeker is not compatible with a weapon intended to be released in multiple round salvos[5].

    Imaging seekers are one technique which provides satellite aided inertially guided bombs with genuine precision capability. The US Navy DAMASK/HART effort is a good example. A typical design for such a seeker will see the bomb seeker take a snapshot of the target surroundings, which is then compared with a preprogrammed image to fix the bomb's position. Once the error is found, the target aimpoint is corrected and the bomb dives into the target. MilliMetric Wave Imaging (MMWI) techniques were demonstrated in the Orca program, while DAMASK demonstrated an uncooled low cost IIR seeker, based on automotive technology. Both techniques have growth potential for attacks on moving targets such as vehicles or shipping (Author/USAF)[4].

    Luoyang Description for 500/250 kg Variants (Cite):

    LS-6 guided glide bomb is a low-cost but highly effective air to surface weapon for standoff precise attack on fixed ground targets, such as airports, seaports, bridges, commander centers, etc. With a wing kit and GPS/INS guidance unit, the conventional low-drag aerial bombs are modified into precision guided bombs with standoff attack ability.

    System features:

    Launched outside mid/short range air defense firepower
    All-weather, day & night attack capability
    Low cost but highly effective
    Fire and forget capability
    Excellent anti-interference capability
    Modular guidance and control unit
    Single target or multiple targets attack capability

    Weapon delivery:

    The LS-6 standoff guided glide bomb (SOGGB) utilizes high-altitude and high-speed launching, high lift-drag ratio aerodynamic configuration and suitable control scheme to ensure a remote gliding control. Before the bomb is dropped, its on-board INS coordinate system must be aligned with that of the aircraft and the fire control system downloads the mission planning into the bomb. Within a specified period of time after the bomb being dropped, the stabilizing system of the bomb starts to work to ensure the bomb and the aircraft being separated safely. And then, the folded-wings expand, putting the bomb into the autonomous flight course, and the on-board control system of the bomb starts to operate to keep the bomb body stable. A combined GPS/INS navigation is adopted during this course. The guidance system translates and calculates the guidance commands and outputs to the autopilot to ensure the bomb flying in a planned trajectory. Based on the relative position of the bomb to the target, the bomb will enter its terminal guidance at a preset distance from the target. On the terminal course of the trajectory, attitude control will be performed via a vertical lead-bias to improve the kill effect.

    Technical data:

    a) Kill Area:
    For normal target:5,000 - 10,000 m2
    For armored targe:100 - 500 m2
    b) Operational Altitude and Speed:
    Launch altitude:4,000 - 11,000 m
    Launch speed:600 - 1,000 km/h
    c) Maximum Launch Range:No less than 60 kilometers with a launch altitude of 11,000 meters and an initial speed of 900 km/h.
    d) Guidance Mode:Combined GPS/INS guidance.
    e) Guidance Accuracy: ≤15 meters CEP


    The following provides a good explanation of the capabilities of glide bombs. The section on "Real Time Maritime Strike" starts at 1:55 in the video. Note the part where the narrator says, "a four aircraft formation releases 64 250-pound weapon simultaneously to destroy a large quantity of enemy targets from a safe distance."
