    Has the US Navy thought this new frigate through? New report raises questions.

    By: David B. Larter WASHINGTON ― The U.S. Navy is rapidly moving toward procuring the first hull in its new class of frigate in 2020, but a new report is raising questions about whether the Navy has done detailed analysis about what it needs out of the ship before barging ahead. The Navy may not have done an adequate job of analyzing gaps and capabilities shortfalls before it set itself on a fast-track to buying the so-called FFG(X) as an adaptation from a parent design, said influential Navy analyst Ron O'Rourke in a new Congressional Research Service report. In essence, the CRS report questions whether the Navy looked at what capabilities the service already has in the fleet, what capabilities it's missing and whether the FFG(X) is the optimal solution to address any identified shortfalls. O'Rourke suggests Congress push the Navy on “whether procuring a new class of FFGs is the best or most promising general approach for addressing the identified capability gaps and mission needs, and whether the Navy has performed a formal, rigorous analysis of this issue, as opposed to relying solely on subjective judgments of Navy or [Defense Department] leaders.” ““Subjective judgments, though helpful, can overlook counter-intuitive results regarding the best or most promising general approach,” the report reads. “Potential alternative general approaches for addressing identified capability gaps and mission needs in this instance include (to cite a few possibilities) modified LCSs, FFs, destroyers, aircraft, unmanned vehicles, or some combination of these platforms.” The Navy is looking to adapt its FFG(X) from an existing design such as Fincantieri's FREMM, one of the two existing littoral combat ships or the Coast Guard's national security cutter as a means of getting updated capabilities into a small surface combatant and into the fleet quickly. A better approach, O'Rourke suggests, would be to make a formal, rigorous analysis of alternatives to its current course. Failure to do so has led to a series of setbacks with the Navy's current small surface combatant program, the LCS. “The Navy did not perform a formal, rigorous analysis of this kind prior to announcing the start of the LCS program in November 2001, and this can be viewed as a root cause of much of the debate and controversy that attended the LCS program, and of the program's ultimate restructurings in February 2014 and December 2015,” O'Rourke writes. O'Rourke further suggests the Navy is relying too much on subjective opinions of Navy and Defense Department leaders, instead of a legitimate analysis. And indeed, the Navy has made rapid acquisition of the new ship the hallmark of the program. “Subjective judgments can be helpful, particularly in terms of capturing knowledge and experience that is not easily reduced to numbers, in taking advantage of the ‘wisdom of the crowd,‘ and in coming to conclusions and making decisions quickly,” O'Rourke argues. “On the other hand, a process that relies heavily on subjective judgments can be vulnerable to group-think, can overlook counter-intuitive results regarding capability gaps and mission needs, and, depending on the leaders involved, can emphasize those leaders' understanding of the Navy's needs.” Read the full report here. https://www.defensenews.com/naval/2018/07/09/has-the-us-navy-thought-this-new-frigate-through-new-report-raises-questions/

    GE Sees Military as Driving Next-Gen Technology

    John Morris PARIS - “Military is where the commercial business was 10 years ago,” says GE Aviation president and GEvice chairman David Joyce. With commercial now set after a decade of renewal (the CF6 replaced by the GEnx, GE90 by GE9X, CFM56 by Leap, CF34 by Passport, and the emergence of the Catalyst turboprop engine), hundreds of engineers and research and development resources are being tasked with creating future generations of military powerplants. Now that the commercial side has proved that new materials such as ceramic matrix composites and technologies such as additive manufacturing are viable, affordable and producible, the military has the confidence to lead the march into new territory. Technologies developed for commercial engines have enabled new military capabilities; in turn, military research and development will enable even newer commercial engines decades into the future. It's a virtuous cycle, Joyce explains. GE is on a roll: it has won the U.S. Army's ITEP competition to replace all T700 engines in Black Hawk and Apache helicopters with the ultra-fuel-efficient single-shaft ITEP next-gen helicopter engine, and it won contracts worth a billion dollars to develop its AETD three-stream adaptable fighter engine as far as demonstrating it on the ground in an F-35. Flight tests could follow, as could eventual reengining of the F-35 fleet. But in any case, GE will be ready with an engine for sixth-generation fighters. In addition, the ubiquitous F404/F414 is being upgraded and continues to win new competitions, including the USAF's new Boeing-Saab T-X trainer and several foreign future fighter programs; the T408 turboshaft powers the new Sikorsky CH-53K King Stallion; and a team is working full time on competing to reengine the B-52 bomber. Business is growing “at really good rates” on both manned and unmanned “black” programs, says Joyce, and hybrid electric is being studied for future applications including UAVs, he adds. He believes GE already has the enabling technologies for the next decade, “but industrializing them is a different thing.” The company has already invested “billions of dollars” in developing a manufacturing and supply chain of materials and technologies for its commercial engines, and this will continue, “Additive manufacturing may be the most disruptive technology that I've seen in the industry in a long time,” says Joyce, “as it opens up a space for designers and for manufacturing that is on a different dimensional plane. It takes a long time to learn how to design with additive. It takes even longer to learn how to manufacture with additive at speed and high rate from a quality standpoint of view. “We are jumping in with both feet because the results on the back end when you get it right are extraordinary,” he adds. “It's going to pay off a whole load more in the next 20 years. This is going to be the best [real return on investment] that we've ever done.” https://aviationweek.com/paris-airshow-2019/ge-sees-military-driving-next-gen-technology
