New undersea drones are smaller, cheaper and can be refueled deep under water

By:

NATIONAL HARBOR, Md. — Bright yellow underwater drones were a visible highlight on the exhibition floor here at the Sea-Air-Space Exposition.

Among the autonomous underwater vehicles (AUVs) featured: a new high-speed, micro-sized vehicle by Hydroid and a subsea drone refueling station by Teledyne Energy.

Hydroid's Remus M3V is substantially smaller than previous models. With a compact, A-size (36-inch long, 4.875-inch diameter) envelope and no fins or appendages, the vehicle can achieve speeds of more than 10 knots and dive up to 300 meters. It can be used in search and survey; intelligence, surveillance and reconnaissance (ISR); and multivehicle missions.

With its variable center of gravity, the Remus M3V can also operate in buoy mode. Its key marketing points are its small size, low cost and compatibility with existing AUV operating systems.

“The Navy always wants more with less,” said Justin S. Reid, business development manager at Hydroid. “They want a smaller vehicle that can do the same things as a larger vehicle, and also the price point to match it.”

Teledyne Energy featured its untethered subsea power station at the exposition, along with its Gavia AUV. The Gavia can perform side-scan sonar operations to capture images of the sea floor. It is intended to travel ahead of Navy fleets and transmit oceanographic data back to the vessels.

Teledyne's subsea power station can remotely refuel the Gavia and other underwater vehicles. Deployable via ship or helicopter, the fuel cell system has an energy storage of 200 kilowatt-hours and an operating depth of 3,000 meters.

Teledyne will demonstrate the subsea power station at the Navy's Advanced Naval Technology Exercise in August.

    Royal Air Force Typhoon jets to receive key sensor upgrade

    By: Andrew Chuter WARTON — With a complex weapons integration program squared away, giving Royal Air Force Typhoon jets more punch, key sensors on the jet could see an upgrade. The RAF's test and evaluation squadron is already test flying the Litening 5 targeting pod in order to optimize its operation by Typhoon pilots. Work is also underway to update and improve the reliability of the jets Pirate passive infrared airborne track equipment, said Andy Flynn, BAE System's Typhoon capability director. Known as Project Centurion, the British late last year completed integration of MBDA's Meteor, Brimstone and Storm Shadow missiles on Typhoon in 47 months. At a cost of around £425 million, or $515.83 million, the program allowed the RAF to stand down the entire fleet of Tornado jets that had provided the primary strike capability. Flynn told reporters during a briefing at the company's Warton combat air site in northwest England Aug. 7 that the sensor work was “the next iteration of Centurion.” “Agile spiral development and keeping the aircraft relevant is the phase we are in. We have done the big leap and it's now about keeping it relevant,” he said. The Tornado was a two-seat aircraft, whereas the Typhoon is single seat. Flynn said the work on the Litening 5 was about easing pilot workload. “What we are doing now is getting the feedback from customer and operations teams on how to make that tasking simpler and really increase the cycle time on ops. We've already got Litening 5 pods up in the air as an iteration and we are seeking feedback from 41 Squadron [the test and evaluation squadron], ” he said. The plan is to get the enhanced capability “out to the front line by the end of next year,” said Flynn. Development phase work is also underway on a new iteration of Pirate as well improving the reliability and robustness of the sensor. “That work is in the development phase and we are doing that over the Autumn period. What we are doing on Typhoon overall is really enhancing the sensors capability as well making the workload easier for the pilot,” said Flynn. The sensor changes are a small part of a wider capability update on the Typhoon to keep aircraft relevant until they go out of service, currently set for 2040. On the horizon for the RAF is a new e-scan radar, known as Radar 2, which is being developed for the British by Leonardo; the new BAE Striker II helmet; and networked enabled weapons. But, Eurofighter, the Airbus, BAE, and Leonardo industrial partnership responsible for the development and production of the Typhoon, is also conducting a review of future potential updates to the fighter. Eurofighter announced at the Paris Air Show in June a deal valued at 53.7 million euros with the NATO Eurofighter & Tornado Management Agency, or NETMA, to undertake a long-term evolution review of the fighter and the EJ200 engine over the next 19 months. NETMA represents the British, German, Italian and Spanish governments. Flynn said there were more than 50 separate candidate technologies being considered by the evolution review. Some of those potential upgrades could also find themselves cross decking to the Tempest sixth-generation fighter now being proposed by the British. Clive Marrison, the industrial requirements director for Team Tempest, the industrial/government partnership leading the next-generation fighter work , said both jets could benefit from close development ties. “Typhoon could benefit from some of the technologies that Tempest is looking at and by the same token Tempest could benefit from some of the technologies that Typhoon is investing in,” said Marrison. For example: Some of the cockpit and helmet work BAE is doing might allow industry to offer some of those technologies back into Typhoon, said Marrison. While the BAE executives were looking into the future for British combat air capabilities, the Typhoon approaches a landmark of sorts to be celebrated. Sixteen years after taking delivery of its first Typhoon, the RAF is preparing to receive the final aircraft ordered for its fleet in the next few weeks, said Flynn. The final aircraft in a British order for 160 Typhoons made its test flight recently and is due to be handed over to the RAF in the coming weeks. Completion of the order leaves 24 aircraft destined for Qatar on the order book for BAE, although it is also building parts of the Typhoons sold to Kuwait by Eurofighter partner Leonardo. Three equipment sets have so far been completed at BAE's Samlesbury plant near Warton, destined for the Leonardo assembly site in Italy. Flynn said the Qatar build program was just getting underway. The 24 aircraft order will see deliveries start in 2022 with completion set for 2024. https://www.c4isrnet.com/global/europe/2019/08/08/royal-air-force-typhoon-jets-to-receive-key-sensor-upgrade/

    Airbus and Germany submit Eurofighter offer to Switzerland

    Bern/ Berlin, 18 November, 2020 – Airbus and the Federal Republic of Germany today submitted their official offer to the Swiss Federal Office of Armaments armasuisse for the sale of Eurofighter aircraft to Switzerland. The offer has been prepared in cooperation with the other Eurofighter nations as well as the industrial partners Leonardo and BAE Systems, and meets the requirements of the so called new combat aircraft (Neues Kampfflugzeug - NKF) procurement process implemented by Switzerland to replace its currently used F-5 and F/A-18 fleet with a more modern model. With the acquisition of the Eurofighter, the Federal Republic of Germany is offering Switzerland the opportunity to deepen its existing military partnership, particularly with regard to the joint training of the two air forces. With the Eurofighter, Switzerland will gain full autonomy in the use, maintenance and application of the data from its aircraft. With more than 660 orders, the Eurofighter is by far the most widely used aircraft for securing airspace over Europe. It is operated jointly by the four partner nations Germany, the United Kingdom, Italy and Spain and is undergoing continuous development. Only a few days ago, Germany itself signed the contract for the procurement of 38 Eurofighters from the latest Tranche 4 and is offering Switzerland the opportunity to lay the foundations for even closer political, economic and security cooperation by procuring the same type of aircraft. Michael Flügger, Ambassador of the Federal Republic of Germany to Switzerland, said: "With this offer, we are inviting Switzerland as our neighbor and reliable partner in security policy and economic matters to protect its airspace with the Eurofighter and to close cooperation between our air forces. For Germany, Switzerland is not just a customer, but a strategic ally with whom we would like to further intensify our already close cooperation. The Eurofighter is the only platform jointly developed and operated by several European nations and would therefore be an ideal solution for Switzerland". Dirk Hoke, CEO of Airbus Defence and Space, said: "With the offer submitted today, we want to show that the Eurofighter is the best overall package for Switzerland. It is the most modern fighter aircraft currently built in Europe and meets all the requirements demanded by Switzerland. By providing construction data and other important information, Switzerland will be given complete and independent control of the Eurofighter, guaranteeing full transparency. With over 200 suppliers in the Confederation, Airbus is already a strong partner for Switzerland, and we look forward to expanding this cooperation even further". @AirbusDefence @Team_Airbus_CH #Air2030 #Eurofighter #NKF #Schweiz https://www.airbus.com/newsroom/press-releases/en/2020/11/airbus-and-germany-submit-eurofighter-offer-to-switzerland.html

    BAE Systems wins $30M in naval IT contracts

    Andrew Eversden WASHINGTON — BAE Systems was awarded two task order contracts to provide and integrate an information warfare platform aboard five U.S. Navy vessels, the company announced Nov. 11. Under the two task orders, worth more than $30 million, BAE will integrate the platforms into the Navy's Consolidated Afloat Network Enterprise Services — the Navy's tactical afloat network. "These two task orders permit us to continue our high-quality, high volume production and integration service, assembling and delivering CANES to the Navy safely and affordably,” Mark Keeler, vice president and general manager of BAE Systems' Integrated Defense Solutions business, said in a statement. “CANES takes advantage of commercial-off-the-shelf insertion, which brings operational agility to the warfighter and savings to the U.S. Navy.” Under the first task order, BAE will produce two fully integrated CANES racks for two Blue Ridge-class command ships, according to the release. That work is expected to be completed by February 2022. The company will provide the same services for two Arleigh Burke-class destroyers and a Virginia-class submarine under the second task order, expected to be completed by March 2022. Work will be performed at the BAE Systems facility in Summerville, South Carolina. Naval Information Warfare Systems Command in San Diego, California, awarded the contracts. BAE Systems also announced earlier this week that it won a five-year, $94 million indefinite delivery, indefinite quantity contract to deliver engineering, test and evaluation support for sensors, in addition to communication, control, and weapons systems for manned and unmanned air platforms. The contract was awarded by the Naval Air Warfare Center Aircraft Division. "We are bringing new advanced technologies such as artificial intelligence and autonomy to the Airborne Systems Integration Division,” Keeler said in a news release. “Our state-of-the-art digital engineering capabilities, and extensive experience in integrating airborne systems are further strengthening the warfighter's ability to meet mission requirements and ensuring combat readiness in the field.” https://www.c4isrnet.com/battlefield-tech/it-networks/2020/11/12/bae-systems-wins-several-naval-it-contracts/
