Creating cross-domain kill webs in real time

Two DARPA-developed technologies - a novel decision aid for mission commanders and a rapid software integration tool - played a critical role in the recent Air Force demonstration of the Advanced Battle Management System (ABMS).

The Adapting Cross-domain Kill-webs (ACK) program and the System-of-systems Technology Integration Tool Chain for Heterogeneous Electronic Systems (STITCHES) were among a number of technologies employed in the Aug. 31 - Sep. 4 ABMS on-ramp demonstration, which involved attacks using live aircraft, ships, air defense batteries, and other assets.

ACK is developing a decision aid for mission commanders to assist them with rapidly identifying and selecting options for tasking - and re-tasking - assets within and across organizational boundaries.

Specifically, ACK assists users with selecting sensors, effectors, and support elements across military domains (space, air, land, surface, subsurface, and cyber) that span the different military services to deliver desired effects on targets. Instead of limited, monolithic, pre-defined kill chains, these more disaggregated forces can be used to formulate adaptive "kill webs" based on all of the options available.

ACK was used in an air defense scenario during the ABMS demonstration, where an air commander faced incoming aerial threats and needed to quickly decide the best way to counter them.

"The ACK decision aid software analyzed thousands of options to form cross-domain kill-webs and recommended the assets for the kill chain and the best command-and-control 'play' to the mission commander," said Air Force Col. Dan "Animal" Javorsek, ACK program manager.

"Once selected, the ACK software sent the 'play' to the C2 Incident Management Emergency Response Application (C2IMERA) and the ground-based Composite Tracker and Classifier (CTC) integrated fire control system that used automated messaging and machine-to-machine cuing over Link-16 to scramble fighters and intercept the cruise missiles."

The machine-to-machine communications to enable this distributed fire control was performed by the STITCHES integration toolchain. STITCHES is a software-only and fully government owned (non-proprietary) toolchain specifically designed to rapidly integrate heterogeneous systems across any domain by auto-generating extremely low latency and high throughput middleware between systems without needing to upgrade hardware or breaking into existing system software.

The toolchain does not force a common interface standard; rather it rapidly creates the needed connections based on existing fielded capabilities obviating the need to upgrade in order to interoperate.

"The DoD is acquiring more and more advanced electronic equipment each year which solve problems unique to our mission," said Lt. Col. Jimmy "Reverend" Jones, SoSITE program manager. "These new systems need to work with systems deployed more than 40 years ago. STITCHES brings force composability directly to the warfighter by allowing data to be shared without system upgrades."

In addition to the ACK and STITCHES technologies, DARPA security and information system staff were able to rapidly accredit and host ACK, STITCHES, and other ABMS software on a secure DARPA network in a matter of days, significantly contributing to the overall demonstration success.

"We were extremely pleased to demonstrate two of many advanced technologies we're developing under our Mosaic Warfare strategy, which is focused on providing fast, scalable, adaptive joint multi-domain lethality," said Tim Grayson, director of DARPA's Strategic Technology Office (STO). "We look forward to continuing to develop and test capabilities that will further enable ABMS."

AEHF-6 protected communications satellite completes on-orbit testing
Sunnyvale CA (SPX) Sep 16, 2020
The sixth Lockheed Martin-built Advanced Extremely High Frequency (AEHF-6) protected communications satellite successfully completed its On-Orbit Test (OOT) period on Aug. 27, 2020. "Successful OOT demonstrates that all space vehicle performance requirements have been met and that we are on track for satellite control authority handover to Space Operations Command before the end of the year," said Erik Daehler, director of Lockheed Martin's Protected Communications mission area. "This is a g ... read more
