Kratos to deliver first XQ-58A Valkyrie production unit in a ‘couple of months’ to USAF By Garrett Reim 2021-05-07T22:23:00+01:00 Kratos Defense & Security Solutions expects to deliver its first production unit of the XQ-58A Valkyrie unmanned air vehicle (UAV) to the US Air Force (USAF) “in the next couple of months”. That’s according to comments from Eric DeMarco, Kratos chief executive, on a first quarter earnings call on 5 May. The company started production of a dozen examples of the stealthy combat UAV on its own dime in 2020, ahead of an anticipated contract with the USAF. Kratos is anticipating that the XQ-58A Valkyrie will move toward operations The Air Force Life Cycle Management Center’s Advanced Aircraft Program Executive Office granted the manufacturer a $37.7 million contract in December 2020 for the XQ-58A as part of the Skyborg programme, an effort to create software and hardware for autonomous control of loyal wingman UAVs that can fly and fight alongside manned fighters, Kratos says on 7 May. The Skyborg autonomy core system, developed by Leidos, is intended to be used to control a variety of UAVs. Kratos declines to comment on the number of Valkyries that would be delivered to the USAF as part of that contract. It had previously used two company-owned XQ-58As to conduct demonstrations and experiments with the service. In February, DeMarco said, as part of a 2020 fourth-quarter earnings call, that he anticipated the company delivering six to 10 production aircraft in 2021, depending on customer demand. “We have a hot production line,” he says, more recently, in the first-quarter earnings call. “We’re not building prototypes.” “I have every expectation that the Valkyrie is going to be deployed”, DeMarco added. Skyborg could reach initial operating capability as early as 2023, the US Air Force Research Laboratory has said. Kratos has said previously that the cost of the XQ-58A would be $2 to $3 million per unit, depending on the quantity ordered. The UAV is classified as an “attritable” aircraft, an asset cheap enough to be lost to combat attrition and then quickly replaced without breaking the bank. The Skyborg programme kicked off in April with the first test of the autonomy core system aboard a Kratos UTAP-22 Mako UAV at Tyndall AFB in Florida. “Follow-on sequence of experimentation events planned over the next several months includes the XQ-58A in the Skyborg configuration supporting a range of experimentation events,” says Kratos. “The aim of these events in the Skyborg Vanguard programme is to integrate autonomous attritable UAV technology with open missions systems to enable manned-unmanned teaming.” The contract also includes integrating multiple “customer-defined mission payloads and customer-defined autonomy” in coordination with Leidos, says the company.

The UK’s crane rental association – the Construction Plant-hire Association (CPA) - has issued a Technical Information Note, a letter and a declaration form to help UK crane rental companies overcome customer demands for a four year overload test that is no longer required or recommended. The overload test is a hang-over from the old UK crane regulations that were abolished in 1998 and replaced with the current LOLER requirements. Many job sites have continued to require a current four year overload test for any crane entering their site. Crane manufacturers have campaigned against regular overload testing for many years, on the basis that it can create fatigue and damage the crane structure while being a important site poor indicator of the cranes structural integrity. The CPA’s best practice guide, launched at Vertikal Days last year and co-published with the UK Health & Safety Executive (HSE) confirmed this, recommending strict, documented thorough inspections by qualified individuals as a better alternative. With many sites continuing to demand the test certificates, the association has now published the TIN- the text of which is reproduced below – along navigate to this website with a declaration form that can be carried in the cab of every crane in place of a test certificate. A PDF version of the TIN will be placed into the Vertikal Library in the section Best Practice Guides. Click here to see or download PDF version Four Yearly Overload Testing of Mobile Cranes In the past, mobile cranes in the UK have frequently been subjected to overload testing at four yearly intervals, in addition to the periodic thorough examinations required by The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER). This is a legacy from the requirements of the old Construction (Lifting Operations) Regulations 1961, which were repealed when LOLER was introduced in 1998. The Approved Code of Practice to Regulation 9 of LOLER states that any testing is at the discretion of the competent person carrying out a thorough examination and that the competent person will decide on the nature of the test and the method of carrying it out. Routine overload testing of mobile cranes has a significant number of disadvantages:- • Most mobile crane manufacturers do not recommend overload tests, except in “exceptional” circumstances and then place a limit on the magnitude of the test load that may be applied; • Repeated overloads may have a deteriorating effect on the crane structure over time; • Most structural failures are the result of fatigue cracks and such defects will not be identified by an overload test. The competent person undertaking thorough examination should be able to discover cracks during thorough examination; • Inspection bodies such as SAFed members do not recommend it, as there is no defined structural or mechanical benefit; • A significant number of insurance policies do not provide cover for a crane that has been overloaded in any circumstances, including overload testing • Periodic overload testing gives a false sense of security to both mobile crane owners and users. A far better indication of the condition of a mobile crane is given by adopting the “defined written scope” approach to thorough examination. The defined scope of thorough examination is specific to an individual crane and should cover at least:- • Examination methods to be employed including special tools, equipment or procedures; • Details of any supplementary reports and tests; The defined scope of thorough examination for an individual crane will comprise of generic elements applicable to most cranes, supplemented by crane specific elements derived from consideration of information including:- • Manufacturer’s information (alerts and technical bulletins); This approach ensures that the thorough examination concentrates on those areas of the crane which are highly stressed, are subject to deterioration or are known to wear rapidly. Further detailed information on the defined written scope of thorough examination approach is given in the CPA Best Practice Guide on the Maintenance, Inspection and Thorough Examination of Mobile Cranes which was produced with the HSE, UKCG, SAFed and a number of other industry organisations.
