China building bridging systems for heavy vehicles

Christopher F Foss, London - Jane's International Defence Review

China's NORINCO and its partners are producing and offering for export a range of bridging systems - including the new HZ21 - that must handle the newer, heavier armoured platforms replacing older Chinese systems.

NORINCO markets a range of mobile bridging systems on tracked and wheeled platforms, but the prime contractor for some of these bridging systems is the China Harzone Industry Corporation (CHIC), which is a subsidiary of the China Shipbuilding Industry Corporation (CSIC).

CHIC confirmed that it has two major production facilities and one research and development facility, with sales of commercial and military bridging systems to more than 40 countries.

The HZ21 military bridging system is deployed by China and referred to by CHIC as a 'fast bridge'. It is transported and launched over the rear of a forward control 8×8 cross-country truck.

Prior to launching the two-part bridge, a stabiliser is lowered on either side at the rear of the platform. The lower part of the bridge is then extended over the gap, followed by the upper part - the complete bridge is then lowered into position.

When fully extended, the 10.5-tonne (11.6 ton) two-part bridge is 21 m (69 ft) long and has a roadway width of 3.3 m; it can bridge a wet or dry gap of up to 19 m. According to CHIC, it can be deployed in fewer than 10 minutes and retracted in a similar time.

The HZ21 can handle tracked vehicles with a gross vehicle weight (GVW) of up to 60 tonnes, or wheeled platforms with a maximum axle load of up to 17 tonnes.

In many respects, the HZ21 is similar in concept and operation to the General Dynamics European Land Systems - Germany (GDELS-G) Rapidly Emplaced Bridge System (REBS) deployed by the US Army, which is transported and launched from a Common Bridge Transporter (CBT).

  • The new Air Force One just racked up its first cost overrun

    The new Air Force One just racked up its first cost overrun

    By: Valerie Insinna WASHINGTON — Boeing will have to pay $168 million out of pocket to cover increased costs on the VC-25B Air Force One replacement program, the company said Wednesday. Boeing attributed the overrun to “engineering inefficiencies” caused by the impact of COVID-19, but Chief Financial Officer Greg Smith said the program remains on schedule with a projected delivery of the first VC-25B in 2024. However, Boeing's quarterly report to the Security and Exchange Commission noted future risk to the program's cost and schedule as a result of the engineering challenges. “We believe these inefficiencies will result in staffing challenges, schedule inefficiencies and higher costs in the upcoming phases of the program,” the company stated in the report. It was not immediately clear how work on the VC-25B program had been disrupted. “That charge was really associated with COVID-19,” Smith told reporters in an April 29 phone call. “As we have folks working virtually — particularly on the engineering side — as well as that's gone, we certainly experienced some inefficiencies that has caused us to re-evaluate our estimates to complete those efforts. And that's essentially what you saw today in our results and the charge associated with that.” Smith added that although the program team has done a “good job” of managing the program in the face of changes caused by the novel coronavirus pandemic and is “executing very well on many fronts,” Boeing could not mitigate the added cost to the program this financial quarter. Air Force acquisition executive Will Roper said he spoke with Boeing Defense CEO Leanne Caret last night about the problem, but because the issue was “late breaking,” he referred detailed questions to the program office. On Wednesday night, the Air Force released a statement that — like Boeing — attributed the cost increase to “engineering inefficiencies.” Just two weeks ago, Roper praised the progress of the program, which used virtual tools to complete its critical design review in March and wrap up a modification readiness review in April. At the time, the program was on schedule with no disruptions due to COVID-19, he said then. The Air Force One replacement drew considerable attention in 2016 after then-President-elect Donald Trump tweeted that the program was too expensive and should be cancelled unless the cost—then projected as more than $4 billion—came down. In 2018, the Air Force awarded Boeing a $3.9 billion fixed-price contract to modify two 747s into the VC-25B configuration. " There has not been an increase to the $3.90B firm-fixed price contract with Boeing or the $5.3B VC-25B total acquisition cost," said Air Force spokeswoman Ann Stefanek. Although the total price of the program is estimated to hit $5.3 billion once ancillary costs such as new hangars and revised technical manuals are included, the fixed-price ceiling on the $3.9 billion deal ensures that Boeing will have to pay for any cost growth incurred while building the two new Air Force Ones. In February, Boeing began making structural changes to two Boeing 747s at its facility in San Antonio, Texas — paving the way for those jets to become VC-25Bs. The jets will also receive upgrades including enhanced electrical power, specialized communication systems, a medical facility, a customized executive interior and autonomous ground operations capabilities. “As planned in the baseline schedule, the next phase of modification is on course to begin in June 2020,” Stefanek said. https://www.defensenews.com/air/2020/04/29/the-new-air-force-one-just-racked-up-its-first-cost-overrun/

    Lockheed Martin And Fincantieri Marinette Marine Awarded Contract To Build Littoral Combat Ship 31

    WASHINGTON, D.C., Jan. 21, 2019 – The U.S. Navy awarded the Lockheed Martin (NYSE: LMT) and Fincantieri Marinette Marine (FMM) team a fixed-price-incentive-fee contract to build an additional Littoral Combat Ship (LCS). LCS 31 will be built in Marinette, Wisconsin, at FMM, the Midwest's only naval shipyard, and is the 16th Freedom-variant LCS ordered by the Navy to date. The team will leverage capital investment and improvement in the shipyard and efficiencies created with serial production to maintain high quality at an affordable cost. "We are excited to continue our partnership with the Navy and FMM to build and deliver capable ships to the fleet,” said Joe DePietro, vice president and general manager, Lockheed Martin Small Combatants and Ship Systems. "With the Freedom-variant in serial production, we continue to enhance efficiency and incorporate capability while maintaining ship and program affordability." Since the LCS program's inception, Freedom-variant LCS production has injected hundreds of millions of dollars into local economies throughout the Midwest. The program supports thousands of direct and indirect jobs throughout the United States, including more than 7,500 in Michigan and Wisconsin. The Lockheed Martin and FMM team is in full-rate production of the Freedom-variant and has delivered seven ships to the U.S. Navy to date. There are seven ships in various stages of construction at FMM. Lockheed Martin's Freedom-variant LCS is highly maneuverable, lethal and adaptable. Originally designed to support focused missions such as mine warfare, anti-submarine warfare and surface warfare, the team continues to evolve capabilities based on rigorous Navy operational testing, sailor feedback and multiple successful fleet deployments. The Freedom-variant LCS integrates new technology and capability to affordably support current and future mission capability from deep water to the littorals.

    Air Force to Spend $31M to Research How Lasers, Energy Weapons Affect Operators

    The Air Force has been testing directed energy weapons—i.e., lasers, high-powered electromagnetic and other radiological weapons—and plans to integrate them into its planes and wargames by next year. But the service still isn't sure how those weapons will affect the people that use them. Air Force Materiel Command announced the award of a $30.8 million contract to General Dynamics Information Technology to establish a rigorous research and testing methodology to establish “scientifically based health and safety standards,” according to a notice on FedBizOpps. The contract is not looking at what happens to humans targeted by directed energy weapons, but rather “to promote maximum use of [radio frequency/high-power microwave] technologies while protecting Air Force personnel from radiation hazards and minimizing negative operational impact,” according to solicitation information archived on BidNet.com. “This requires an extensive research program in dosimetry and bioeffects of ... radiation.” The research contract also calls for GDIT to create “exposure assessment tools” that will alert operators when they have had too much contact with certain forms of energy radiation and preempt over-exposure. The results of this research will be integrated with U.S. and international health and safety standards and adopted by the Air Force Surgeon General for Occupational Health and Environmental Safety. “Our goal is to provide the USAF with the world's best ... radiation bioeffects research and science-based exposure standards, allowing maximum safe exploitation of [directed energy] for national defense,” the solicitation states. https://www.nextgov.com/emerging-tech/2019/09/air-force-spend-31m-research-how-lasers-energy-weapons-affect-operators/159675/
