It shouldn’t be that much of a surprise, as Harpoon entered service in 1977– yes, almost 50 years ago– but the new Harpoon Coastal Defense System (HCDS) was validated at its Developmental Test (DT-1) at Point Mugu Sea Range (PMSR) in July 2026, “validating the system’s ability to engage and neutralize maritime threats.”

During the event, the Harpoon missile successfully launched from land and engaged the target vessel in near-shore/littoral waters.

It is planned to ship these to Taiwan, which has a $2.3B program to field 100 HCDS launchers and 400 missiles– a pretty good way to keep the local littoral their local littoral.

It should also be noted that the background concept has been extensively validated over the years, with the Royal Danish Navy fielding two 8-missile batteries of Scania 113M/320 truck-mounted quad-packed Harpoons from 1988 to 2003.

Plus, Ukraine received 20 Harpoons in 2022 from donations by Denmark, the Netherlands, the U.S., UK, and Spain for use in ground-based launchers, though little has been seen of them. Like, literally. The Ukrainians conceal them inside cargo containers to avoid the drone ka-boom.

The Danes also loved to heavily camouflage their Harpoons, so you can be sure the Taiwanese will be sure to do the same.

But, why?

So why bother with a land-based trailerable Harpoon when the Marines already have the smaller Navy-Marine Expeditionary Ship Interdiction Systems (NMESIS) ground-based system which carries two Kongsberg Naval Strike Missiles?

Well, throw weight for one. While the 13-foot/800-pound NSM is a newer and more streamlined missile, it only has a 264-pound warhead, while the 15-foot/1,500-pound Harpoon totes 500 pounds of boom and delivers it with more kinetic energy by virtue of mass and speed.

Yes, NSM has a longer published range of 100nm while the RGM-84L-4 Harpoon Block II has a published range of 75nm, but keep in mind those are public figures.

Of course, the 8-ton NMESIS with its two missiles is CH-53E/K (hoist) or C-130 (internal) aircraft compatible and built to operate in much more austere environments, ready to pop off an LCU, LSM, or LCAC onto a beach while the HCDS, based on the same HEMTT trailer as the Army’s THAAD, is more of a C-17/industrial-grade roadway kinda thing, as its weight is likely closer to 35 tons.

While HCDS is set to deliver to Taiwan to complement indigenous HF-2 and HF-3 anti-ship launchers, it might not be a bad idea for the USN to invest in a few batteries of these, for a just-in-case type of scenario. Put them in the reserves with two Marine Reserve Artillery Battalions, one staged on the East Coast, the other on the West.

Speaking of Marines and Harpoons, since you came this far, how about these great very recent shots of VMFA-232 “Red Devils” F-18C/Ds out of MCAS Iwakuni conducting an anti-ship exercise, complete with two AGM-84s under the wings along with a pair each of Sidewinders and AMRAAMS for emergency use.

Nice to see the classics.
