Lockheed Martin LMXT (KC-Y Bridge Tanker)

Aerial Refueling Tanker Aircraft Proposal [ 2030 ]

The LMXT is the Lockheed Martin submission into the KC-Y Bridge Tanker field being sponsored by a United States Air Force requirement.

Authored By: Staff Writer | Last Edited: 05/20/2022 | Content ©www.MilitaryFactory.com | The following text is exclusive to this site.

The LMXT is Lockheed Martin's attempt to secure the standing KC-Y "Bridge Tanker" requirement of the United States Air Force (USAF). The platform is built atop the proven framework of the French Airbus A330 passenger airliner - the A330 Multi-Role Tanker Transport (MRTT) derivative to be exact - which has proven itself a capable player operationally in the aerial-refueling realm through various European /Western air powers including Australia, France, Germany, and the United Kingdom. The competition seeks a "bridge" product between an aging USAF refueling fleet and the in-delivery Boeing KC-46A "Pegasus" tanker product (based in the Boeing Model 767 airliner).

Deliveries of the winning product are expected sometime after 2029 by the service. The LMXT is billed as a strategic-level solution utilizing all-modern and advanced technologies to see the role through. Key components of the Lockheed proposal include the Joint All-Domain Command and Control (JADC2) open-system architecture, increased operating ranges, increase fuel payload, and a digitally-controlled Fly-by-Wire (FbW) / Automatic, Air-to-Air Refueling (A3R) boom offering advanced camera and vision sensors. An enhanced defensive countermeasures system will be carried by the aircraft for heightened survivability in contested airspaces/warzones. The airframe will also feature networked communications between all battlefield assets - from satellites and warships to allied fighters and bombers.

The use of the popular French A330, coupled with the proposed Lockheed Martin add-ons, hopes to ensure speedy development of the needed aircraft.

The LMXT will be capable of refueling all, if not most, of the USAF's current in-service aircraft including F-22 and F-15 air superiority fighters, F-35A strike fighters, F-16 lightweight fighters, B-1 strategic bombers, C-17 heavy airlifters, and E-3/E-7/P-8 special-mission platforms.

Using the Airbus A330 as its foundation, the aircraft will continue much of the airliners form and function; a pair of underslung, non-afterburning turbofan engines are set under each swept-back wing mainplane (capped by fuel-saving winglets). The flight deck resides in its traditional place over the nose and the tail unit encompasses a large-area vertical fin with low-set, upwards-cranked horizontal planes. As in the commercial A330 series, a retractable tricycle undercarriage will provide ground-running support.

Specifications as currently estimated (2021) of the LMXT include a length of 193 feet, a wingspan of 198 feet, and Maximum Take-Off Weight (MTOW) of 533,500lb. The complete fuel load will weight 271,700lb. Cruising will be around the Mach 0.81 range and the mission endurance window is set to reach 19.5 hours, offering nearly round-the-clock support for ongoing operations.©MilitaryFactory.com
