The Navy’s Unmanned Surface Ships Will Be Power-Hungry

US Navy unmanned systems can be used for advanced operational surveillance or as sensor nodes within a larger multi-domain warfare network. Missions like these will require unmanned systems to be energy independent and able to conduct operations without being refueled or resupplied.

Large unmanned surface combatants will require significant amounts of power to maintain radars, sonars, other sensors, propulsion, and command and control equipment. Power sources must also be reliable and resilient.

A system under development is called Integrated Power and Energy Systems (IPES). It seeks to optimize the storage, efficiency and distribution of power and energy. The IPES can enable a range of ship functions such as high power laser weapons, new generations of radar and even electric propulsion for manned and unmanned systems. Improved energy storage and generation can extend and strengthen the digital network between ships and drones to extend mission standby time, strengthen communication connections, and distribute factor-sensitive combat data. time. IPES could allow a ship to operate at ideal speeds while storing energy.

Navy Captain Pete Small is the Maritime Unmanned Systems Program Manager. Small has been developing new unmanned platforms, such as large and medium unmanned surface ships (USVs), for many years. Small emphasized the need for open architecture and advanced interfaces to enable technology growth, sensor payload modularity, continuous upgrades, and on-board power management.

IPES is future-ready, which means it is designed to be upgraded. This is partly why interfaces are developed to allow maximum interoperability. The Navy is currently preparing a special “integration lab” where new technologies can be tested and refined before being taken on board a ship. Kevin Knowles, Northrop Grumman USV Campaign Manager, explained that efforts to design efficient and functional interfaces can be supported to great effect by the Integration Lab.

Increased IT automation can improve overall vessel efficiency and performance. It’s one of the reasons Northrop Grumman developers work to ensure that the system and networks that breathe life into the IPES architecture themselves are hardened against potential intruders or cyberattacks.

“You need to be able to make sure no one gets in there and starts messing with your delicate automation systems or impacting your written navigational systems,” Knowles said. “So we did a lot of thinking and providing information on cybersecurity.”

All of this is intended to support, activate and reinforce the Navy’s distributed maritime operations strategy. Maritime warfare is expected to be more dispersed and defined to a large extent by revolutionary weapons and sensors with much greater range, accuracy and data transmission capability.

Northrop Grumman’s IPES developers strive to meet the energy needs of dynamic weapons and sensors, autonomy, computer automation, and unmanned systems. These technologies should form the conceptual, operational and tactical basis of modern maritime warfare.
