Coalition Kill Chain for the Pacific: Lessons from Ukraine

Russia’s war in Ukraine offers a critical case study on why—and how—to build a more robust kill chain that leverages partners’ and allies’ capabilities. A more expansive satellite communications (SATCOM) network that enables a real-time integrated common operational picture (COP) will be necessary to generate the relative combat power advantage over the People’s Liberation Army (PLA). Russia initiated combat operations in Ukraine with cyberattacks on SATCOM to disrupt Ukraine’s kill chain—the methodology for finding, fixing, targeting, tracking, engaging, and assessing (F2T2EA) an adversarial objective.

Ukraine’s kill chain—the methodology for finding, fixing, targeting, tracking, engaging, and assessing (F2T2EA) an adversarial objective. The United States, alongside partners, allies, and industry, was able to blunt Russia’s invasion by reconstructing Ukraine’s SATCOM network and sharing critical intelligence. However, the kill chain architecture leveraged against Russia does not exist in the first island chain of the western Pacific.

…………… To achieve the capability required to deter the PLA, the Department of Defense (DOD) must further develop SATCOM architecture in the first island chain and expand partners and allies’ access to the COP to build a coalition kill chain that can mass fires.

……….. the United States had to create more permissive policy for intelligence sharing for more effective targeting. Furthermore, kill chains in the Pacific are more dependent on SATCOM as submarine internet cables are more vulnerable and likely already compromised by China.

……. First, to enhance U.S. SATCOM architecture, the DoD could begin to supplement geosynchronous orbit satellites by proliferating low-earth-orbit and medium-earth-orbit satellites. This would reduce vulnerabilities related to adversarial space operations and expand SATCOM range and resiliency. SpaceX’s Starlink functions off the same principle of a mesh networks of low-earth-orbit satellites.

Second, the United States could use partner and allies’ satellite networks and make policy more permissive with intelligence sharing. In March 2022, the Department of Defense announced its Joint All-Domain Command and Control Implementation Plan with the 5th line of effort to “Modernize Mission Partner Information Sharing.” The intent is to enhance the ability to integrate partner and allies’ data for all-domain coalition operations. After all, the value in integrating systems is only as good as the real-time tracks being shared. To build a coalition kill chain, U.S. policy will have to become more permissive with intelligence sharing among partners and allies.

Structure of the Multinational Kill Chain

The United States will also need to create a methodology for building a multinational COP and integrated fires network. Tactical-level forces across the partner and ally network must evolve to contribute more to operational and strategic-level fires and effects. This effort is twofold: first, the joint force could expand partners and allies’ access to Type-1 Link-16 cryptography, so they are built into the operational tasking link; and second, it could reduce constraints on protocols and pathways for sharing information.

The first effort would integrate partners and allies into the tactical data link router used by the U.S. joint force, also known as the Joint Range Extension Applications Protocol. This would require access to the joint Link 16 architecture by assigning partners and allies a cryptographic variable logic label via an operational tasking data link (OPTASK LINK). Access to the Link 16 architecture would provide a shared COP capable of integrating national technical means for finding and fixing targets and cuing assets to track them.

……………………………………………Once the multilateral kill chain is built, it must be rehearsed with common understanding of joint war-at-sea terminology among partners and allies. War-at-sea, zones of action, and zones of fire must be standardized in planning to achieve a common lexicon. The Global Area Reference System is also key to orientation and understanding the battlespace. Rehearsing multilateral plans for fire, specifically including protocols for authorities, and collaborating on battle damage assessments are necessary to achieve true integration………………………………………………….. https://www.usni.org/magazines/proceedings/2023/july/coalition-kill-chain-pacific-lessons-ukraine
