The U.S. army seems to have anticipated the menace posed by Chinese language balloons and has practiced tackling them for at the least two years, in keeping with Pentagon finances paperwork describing a categorised program generally known as TRIPPWIRE. These additionally point out that somewhat than there being a ‘balloon hole’ because the Wall Avenue Journal not too long ago steered, the U.S. army could also be properly forward on this expertise – although its balloons are used somewhat in another way from the Chinese language ones.

TRIPPWIRE is a contrived acronym from “Tactical Responsive Intelligence, Surveillance, and Reconnaissance (ISR) Platforms and Payloads Watching Remoted Distant Environments.” It’s a multi-year effort utilizing stratospheric balloons as long-range, long-endurance remark platforms.

The scant particulars are supplied in a program description within the Analysis and Growth finances of the Workplace of the Secretary of Protection, a company which manages actions the place Military, Navy, Air Power and House Power work collectively. TRIPPWIRE is described as “a DoD initiative to operationalize the stratosphere by providing elevated demonstrations of high-altitude ISR and communication programs.”

The section “operationalize the stratosphere” is a mantra for this program: the view is that experiments and prototypes have already proven the worth of steerable stratospheric balloons in a position to navigate to a location and stay over it, now could be the time for the providers to make use of them in operations.

Plans present TRIPPWIRE was integrated into “joint multi-domain demonstrations workouts, similar to Northern Edge 21, Talisman Sabre, or Pacific Europe/Pacific Defender” to point out “operational utility in operationally related environments with direct warfighter involvement and suggestions.” In different phrases, getting troops to make use of the programs in practical wargames.

TRIPPWIRE’s major focus is in utilizing high-altitude balloons as sensor platforms and communication relays, offering comparable functionality to satellites however for a protracted interval and from a lot nearer vary. As well as, the doc notes that “A Counter-Stratospheric Operations experiment will likely be carried out inside TRIPPWIRE” – in different phrases, taking down balloons operated by opposing forces. In a wargame, this may most probably contain a simulated kill, however would have examined the U.S. capability to detect, observe, intercept and get into firing place with a digital missile towards an actual goal.

Media releases from Northern Edge 21, a large wargame involving Air Power, Military, Marines and Navy items and held in Alaska in Might 2021, present that stratospheric balloons had been concerned. Photographs had been captioned with minimal info: “Floor crew members put together and launch an remark balloon” is a typical instance.

Video from Northern Edge 21 reveals a balloon strikingly just like the Chinese language one shot down off South Carolina, with a spherical envelope and an array of photo voltaic panels.

The U.S. has denied that it flies spy balloons over China, and whereas there could also be an espionage balloon program, the army program is directed in direction of tactical use. In line with the FY23 finances paperwork on the OSD’s Stratospheric Balloon program: “Demonstrations deal with evaluating how the Joint Power can leverage … operationalization of the stratosphere to refine hypersonic and long-range fires kill chains to counter time-sensitive targets.”

In different phrases, utilizing balloons to identify issues like transferring autos or, particularly, cellular ballistic missile launchers. ‘SCUD looking’ throughout Desert Storm proved to be largely futile, as Iraq’s cellular SCUD launchers had been in a position to conceal below bridges and inside buildings, firing missiles and getting out of the world earlier than they may very well be focused. Remark balloons teamed with new hypersonic missiles may be capable to find and strike such cellular items earlier than they may perform an assault.

Paperwork additionally point out one particular piece of {hardware}, stratospheric balloon known as COLD STAR, for Covert Lengthy Dwell Stratospheric Structure, “outfitted with autonomous navigation, excessive constancy sensors, and on board algorithms to facilitate tasking, assortment, processing, exploitation, and dissemination.” This has been finishing up operational demonstrations since 2020. The phrase ‘Covert’ means that COLD STAR might have some stealth options making it tough to identify.

Photographs launched throughout the Thunder Cloud live-fire train in Andoya, Norway, in September 2021 present the launch of an unspecified Raven Aerostar stratospheric balloon; in keeping with the caption, this was used to offer goal co-ordinates for long-range fireplace. This firm has supplied stratospheric balloons for NASA and numerous army applications.

There may be little info obtainable – “Particulars of this mission are categorised,” in keeping with the outline of the Stratospheric Balloon program. However there is sufficient to present that the Pentagon has been actively pursuing this expertise for, is already flying the {hardware}, and has a reasonably good concept about the best way to convey it down.

Which means that the latest shoot downs have been considerably extra calculated than the early breathless reviews steered. Nevertheless it’s an excellent guess that ‘counter-stratospheric functionality,’ as soon as a really area of interest curiosity, is now having fun with much more consideration than beforehand.
