Navy divers to have automated logging from worn dive computers

By Bobby Cummings, Office of Naval Research,

ARLINGTON, Virginia (NNS) -- For U.S. Navy deep-sea divers, time is of the essence. While operating 100 feet down, with little to no natural light—often in frigid temperatures and limited oxygen—time is everything.

But for divers, time remains a precious commodity on the surface as well.

For years, military divers have had to manually write and log information from dives while at sea into a system known as the Dive/Jump Reporting System (DJRS). Manual entries can be time-consuming and allow human error.

Enter the Office of Naval Research (ONR) Global TechSolutions program, a rapid-response science and technology program focused on solutions to problems submitted by Sailors and Marines.

ONR TechSolutions and industry partners have created a new tool called the Scuba Binary Dive Application (SBDA) 100 to digitally plan, record and report dive-profile information to DJRS. The application will accelerate the process of logging and uploading dive information, and will help eliminate potential data-entry mistakes.

The idea originated from Force Master Diver Scott Brodeur, Naval Expeditionary Combat Command.

“Scott has completed over a thousand dives during his career and he recognized the need to make the logging and reporting process more efficient for his peers,” said Jason Payne, TechSolutions acting program manager.

The SBDA 100 is a software application on a ruggedized tablet used to log, compute and accurately compile dive-profile data.

The data, collected from a wrist watch that divers wear during operations called a Navy Diver Computer, includes dive site conditions, equipment used by the divers, dive events, such as, when a diver left the surface or left the bottom of the ocean floor, and if the dive required decompression stops. SBDA 100 syncs this information and automatically uploads it to DJRS.

“For years, I witnessed how many hours it takes to manually log dives—watching the young guys that have to—at the end of a long 12 to 14-hour-day—come back and manually go through the dive logs and write everything down, and double check it and triple check it,” said Brodeur.

During a recent training exercise in the Gulf of Mexico, Brodeur, the Naval Experimental Dive Unit and other U.S. Navy divers stationed around the globe had the opportunity to test the technology for the first time.

“The designers gave me a crash course on how to operate the technology,” said Chief Navy Diver Marshall Goble, ship repair facility, Yokosuka, Japan. “I used the device as a primary but still used the ‘old school' way and wrote down the information as well. Both calculations came out 100 percent accurate. I found the tablet easier to use, and I have no doubt it's going to streamline efficiency.”

Throughout the process of the development of the SBDA 100, ONR TechSolutions has worked in conjunction with Space and Naval Warfare Systems Command (SPAWAR) Atlantic; industry partner Intelligent Automation Inc.; and Naval Surface Warfare Center (NSWC) Panama City, which is the home of the U.S. Naval Diving and Salvage Training Center. SPAWAR served as the principal investigator and NSWC Panama City provided technical support and hosted the training and demonstration of the SBDA 100 at sea.

“The technology has tested very well,” Brodeur said. “It's a testament to the value of the ONR TechSolutions program and everyone who worked on this project. Witnessing this idea come to fruition and have it be built, demonstrated, designed and ready for use is pretty exciting.”

    NATO's East Is Rearming, But It's Because of Putin, Not Trump

    Ott Ummelas Donald Trump has taken credit for a rise in military spending by NATO states, but in the alliance's eastern reaches, it's his Russian counterpart, Vladimir Putin, who's driving the rearming effort. Last month, North Atlantic Treaty Organization Secretary General Jens Stoltenberg thanked the U.S. President for “clearly having an impact” on defense spending by allies while Trump said his demands had added $41 billion to European and Canadian defense outlays. But the jump in acquisitions behind the former Iron Curtain of aircraft, ships and armored vehicles began when Russia annexed Crimea from Ukraine, well before Trump's 2016 election victory, according to analysts including Tomas Valasek, director of Carnegie Europe in Brussels. While the median defense expenditure of NATO members is 1.36 percent of gross domestic product, below the alliance's requirement of 2 percent, eastern members comprise seven of the 13 members that are paying above that level. “Countries on NATO's eastern border do not need Donald Trump to boost defense spending,” Valasek said. “They decided this long before he came to power. The spending boost was because of a president, but it was Vladimir Putin, not the U.S. President.” Constant overflights by Russian aircraft into NATO airspace, cyberattacks on government and military installations, wargames on the borders of the Baltic states and accusations that Russia was behind a failed coup in newest member Montenegro have put NATO's eastern quadrant on alert for what it says is an increasingly expansionist Russia. Of the 15 members exceeding the bloc's guideline that 20 percent of total defense spending should go to equipment, six are from eastern Europe. At the time of the NATO summit in Brussels, Romania said it would buy five more F-16s from Portugal, raising its squadron to 12, after it signed a $400-million deal to acquire a Patriot missile air-defense system with Raython in May. The country of 20 million people bordering Ukraine, Moldova and the Black Sea plans to buy 36 more F-16s, four corvettes, at least 3,000 transport vehicles and coastal gun batteries over the next five years. Slovakia also announced the purchase of F-16 fighter jets at the summit to replace its aging Russian Mig-29s in a deal that was years in negotiating. And last month, Bulgaria asked for bids for at least eight new or used fighter jets by October at a total cost of 1.8 billion lev ($1 billion). By end-2018, the government in Sofia plans to buy 1.5 billion lev worth of armored vehicles and two warships for 1 billion lev. Neighboring Hungary said in June that it had agreed to buy 20 Airbus H145M multi-purpose helicopters, the country's largest military purchase since 2001. NATO's European members are expected to spend around $60 billion on equipment this year, with the 13 eastern members accounting for about 10 percent, said Tony Lawrence, a research fellow with the International Center for Security and Defense in Tallinn. The newer members will together spend about $2 billion more on equipment this year than last, he said. According to NATO, seven of its 10 biggest spending increases will be in the east. “Since these nations' membership in NATO, there has been a clear inclination to foster and strengthen their link with the U.S.,” said Martin Lundmark, a researcher with Swedish Defense University in Stockholm. “By procuring strategic defense systems, they willingly become interdependent and inter-operable with the U.S.” https://www.bloomberg.com/news/articles/2018-08-13/nato-s-east-is-rearming-but-it-s-because-of-putin-not-trump

    Les budgets de la Défense ont atteint des records en 2021

    Selon la dernière étude du Sipri, l'Institut international de recherche pour la paix, basé à Stockholm, sur les dépenses militaires, les pays consacrent désormais 2,2% de leur PIB à leurs armées et les dépenses militaires mondiales ont atteint précisément 2 113 Md$ (1 966 Md€), une hausse de 0,7% par rapport à l'année précédente. A eux seuls, les Etats-Unis et la Chine concentrent plus de la moitié des dépenses militaires mondiales. Avec un budget de 801 Md$ (745 Md€), les Etats-Unis ont accru leur effort de recherche et développement de 24 % en termes réels depuis 2012, quand l'achat d'armes baissait de 6,4 %. De son côté, la Chine réalise la plus forte croissance du top 5 mondial, avec une progression de ses dépenses de 4,7% pour atteindre 293 Md$ (273 Md€). En se lançant dans un grand programme de modernisation de l'équipement de ses armées, la France grimpe de deux places dans ce classement pour atteindre le 6ème rang mondial. L'Europe a augmenté globalement ses dépenses d'armement de 3% par rapport à l'année précédente. L'objectif fixé par l'OTAN à ses membres de consacrer au moins 2% de leur PIB à la défense se concrétise peu à peu : huit d'entre eux respectent ou dépassent le seuil, contre trois en 2014.
