ABERDEEN PROVING GROUND, Md. — As soldiers at every level become more connected and devices proliferate, the strain on the field-level power grid increases.
Staff at the Army's Research, Development and Engineering Command dove into the finer details of power management, auto tuning and analytics to drive how soldiers use power in the field.
Most of that work is focused around the tactical microgrid, basically the network of power that runs tactical operations.
Think thick cables, generators and all the power that lets the computers, radios and networks run to digest the vast amounts of information, communication and other electrical needs consumed by a modern military.
In the not-too-distant past, generator operators and technicians played a sophisticated guessing game that involved a clock, multimeter, flashlight and notepad to measure and mark which power supplies were running, at what level, and where they were on fuel.
But by adding digital capabilities and software-driven devices into the guts of what were simple analog generators and boxes full of copper wiring and switches, they have created a type of brain for what was formerly a mindless system.
That's resulted in the new Advanced Medium Mobile Power Source, the first new generator for the service in years.
The combination of that device, controllers within the system, and advanced software gives the soldier a centralized place to monitor and manipulate the different devices in the microgrid that will help the flow of power move to where its needed.
“I can tell you if you're using too many lights or computers on one of those three phase lines and if you're out of balance,” said Bradley Stanley, an RDECOM computer scientist.
By using software to make those readings, the end user can then shift the strain to other parts of the system, maximizing power output and fuel use for what can be 24-hour, days long operations.
Another software improvement in “autotuning” is helping make what can be a multi-person with expert training four-hour job into an automated procedure handled by the computer.

The US Air Force is asking the US Congress to let it retire 201 aircraft in fiscal year 2022, in order to reinvest savings from not operating and maintaining those aircraft into research and development, as well as procurement of next-generation aircraft and weapons.

The US Navy has announced its intention to block-buy two Ford-class aircraft carriers, US Senate Armed Services Committee member Tim Kaine has confirmed. The Ford-class warships are equipped with electromagnetic-powered aircraft launch system (EMALS) and are expected to replace Nimitz-class carriers, which have served the US Navy for more than 40 years. Welcoming the announcement, Kaine said: “I'm thrilled the navy has decided to pursue a block-buy for aircraft carriers, something I've been advocating to save billions in taxpayer dollars and offer more certainty to the Hampton Roads defence community. “This smart move will save taxpayer dollars and help ensure the shipyards can maintain a skilled workforce to get the job done. Newport News builds the finest carriers in the world, and I know they are ready to handle this increase in work as we make progress toward the navy's goal of a 355-ship fleet.” In June 2017, Huntington Ingalls Industries' (HII) Newport News Shipbuilding division delivered the first Ford-class aircraft carrier, Gerald R Ford (CVN 78), to the US Navy following completion of acceptance trials in May. The USS Gerald R Ford was built at a cost of $13bn and commissioned in July 2017. According to HII, the Ford-class carriers have a nuclear power plant, a redesigned island, electromagnetic catapults, and improved weapons movement, as well as an enhanced flight deck capable of increased aircraft sortie rates. The navy expects to spend around $43bn to build the first three ships in the class. Deployment of the ship is estimated to result in $4bn in total ownership cost savings for the navy. Last year, the navy asked HII for detailed pricing on the cost of two aircraft carriers. https://www.naval-technology.com/news/us-navy-ford-class-aircraft-carriers/
