JOINT BASE PEARL HARBOR-HICKAM, Hawaii–The Pentagon is accelerating the development of new breakthrough technologies and ramping up exercises with regional partners as it prepares for an anticipated increase in aggressive military activity from China in the South China Sea.
The moves are designed to deter a Chinese invasion of Taiwan, which many experts believe is coming by 2027.
“Until about a year-and-a-half ago, the presence of [Chinese] Navy east of Taiwan was not a regular, constant thing. “They’re always there now,” a senior official in the defense sector told Defense One. Those sorts of stunts from China aren’t just to show force, the official said, but also an effort to exhaust Taiwanese defense capabilities and ability to respond.
“It’s just wearing out Taiwan’s air force for the air stuff and the navy for all of this contiguous presence, because you can’t really let it go unchallenged,” the U.S official said. The Chinese are able to use a greater number of planes, and have more flying capability. It’s just running the poor Taiwanese air force into the ground.”
China’s steadily increasing military maneuvers around Taiwan are, in part, a response to increased U.S. political interaction with Taiwan, including then-U.S. House speaker Rep. Nancy Pelosi’s, D-Calif., visit to Taipei in August 2022 and Taiwan President Tsai Ing-wen’s meeting with current U.S. House Speaker Kevin McCarthy, R-Calif., in April.
“Between the beginning of August and the end of the year, I want to say that we’re at about 200 centerline crossings,” or instances where Chinese vessels crossed into Taiwanese waters, the senior U.S. official said. “So a clear and deliberate escalation…as a signaling tool.”
The official expressed concern that China may attempt another bullying naval maneuver around Taiwan later this summer, in response to continued outreach to Taiwan from U.S. lawmakers.
“Members of Congress travel when Congress is in recess,” the official said. “So it looks like an intentional pile-on that’s, in fact, just driven by the Congressional calendar and August recess.”
In 2021, Adm. Philip Davidson, then-commander of U.S. Indo-Pacific Command, said China could make a play for Taiwan by 2027–the year by which China’s President Xi Jinping has ordered his military to be prepared for a possible invasion. Current INDOPACOM head Adm. John Aquilino has neither endorsed nor refuted the date, at least not publicly.
But an invasion is far from a certainty, according to the official who spoke to Defense One, especially if President Xi can absorb Taiwan politically with no bloodshed. Still, that 2027 time frame looks like the most attractive date for an invasion based on a variety of factors, experts say. Perhaps the most important is that China’s weapon modernization efforts are scheduled to reach a key maturity point then–about two years before Taiwan completes similar efforts designed to make an invasion too costly for China to attempt.
To better deter that potential Chinese invasion, the Defense Department is accelerating key efforts in joint all-domain command and control, or JADC2, in the region, and INDOPACOM is working to increase the number and scope of its exercises and to bring in more partners to present a broad unified front against Chinese aggression.
Additionally, the U.S. Air Force is in the midst of its largest ever mobility exercise in the Pacific, practicing how it would move troops and supplies around the expansive region during a war with China.
Military leaders often describe JADC2 in terms of a vision for the later half of the decade, when massive data flows to artificial intelligence agents will enable commanders to collapse the time it takes to identify targets and dispatch them with the most appropriate weapon on the battlefield, regardless of whether that weapon belongs to the Navy, Army, or Air Force, and whether if it’s a manned jet, drone, or a missile battery.
But Deputy Defense Secretary Kathleen Hicks, who is visiting military and defense officials in Hawaii this week, pushed back on the idea that JADC2 was a future endpoint.
“Some folks like to talk about JADC2 as though it’s far off and it’s not something we’re advancing every day,” she said.
Hicks has already launched a series of efforts to greatly speed up actual JADC2-enabling technologies to the battlefield. One effort, the Rapid Defense Experimentation Reserve, or RDER, uses reserve funds under the control of the undersecretary–$687 million in the current budget–to boost new technologies that have relevance to the joint force, rather than a specific service.
A sample of these early technologies include electronic warfare kits which can detect or emulate radio and electronic signatures from a variety of ship, plane, etc. To convince enemies to spend scarce resources investigating phantom tanks and jets. Another early RDER prototype viewed exclusively by Defense One allows operators to pass data through unsafe IT networks, a major concern in the broader region as China has a growing share of key portions of telecommunications infrastructure even in nations friendly to the United States.
Hicks said efforts like RDER are critical to making joint, all-domain warfighting a reality as soon as possible.
A second senior defense official outlined a number of key mission threads that RDER will address, including integrated air and missile defense, surface warfare, distributed re-supply, long-range fires and logistics under adverse enemy conditions.
INDOPACOM also wants to accelerate key technology areas in order to run more exercises with service branches and partner nations. A new mission partner is being developed as a virtual destination that will allow INDOPACOM to use all data, including from allies like the Philippines and all services. One defense official who spoke to Defense One said INDOPACOM plans to conduct its first demonstrations of the capability in September with Japan. A demonstration with Australia would follow soon after.
Another effort, the Pacific Multi-Domain Training and Experimentation Capability, will significantly increase the number of virtual exercises INDOPACOM can conduct and will allow a more diverse set of players to participate in real wargames virtually. For instance, ship crews could practice how they might respond to a certain scenario alongside other air, land, sea, and space forces without having to physically move a ship.
“We spend a lot of time here on this decision-advantage issue, which is how to bring information to the battlefield at speed and in a scale that can make a real difference. If you are part of INDOPACOM you might have a specific way that you would like to manage the visualization of the theatre, and we will enable you to do that,” Hicks explained.
While the United States is driving these technology efforts, officials said partner nations want to play a role too, particularly in a more robust schedule of joint exercises as they seek to counter China’s illegal fishing and bullying by the Chinese coast guard.
“Now they are coming to us,” a senior military official said.
