China's Missile Test Threatens U.S. Mainland

Jason Simpkins

Posted July 7, 2026

Yesterday, China’s military did something it rarely does.

It fired a ballistic missile from a submarine into the Pacific, setting off alarm bells throughout the region.

New Zealand Minister of Foreign Affairs Winston Peters called the test “unwelcome and concerning.”

Australian Foreign Minister Penny Wong said the test was “destabilizing to the region.”

And the Japanese government said it had “serious concerns regarding China’s increasingly active military activities.”

However, it’s not just China’s Pacific neighbors that should be worried. There were potential implications for the United States too.

You see, China’s Navy has two types of submarine-launched ballistic missiles — the JL-2 and the JL-3. And the latter has sufficient range to reach the continental United States from waters off the coast of China.

So the implications of this test extend far beyond the Pacific region. And crucially, the incident further cements the case for President Trump’s Golden Dome initiative.

Beijing Is Building an Arsenal, Not a Deterrent

This submarine launch didn’t happen in a vacuum.

China now fields roughly 3,450 missiles of all range types, according to the Defense Intelligence Agency. Its nuclear warhead count has already topped 600, with another 400 expected within five years.

Then there’s the hypersonic problem…

The Pentagon says China has fielded the DF-27 — a conventional missile with a stated range up to 8,000 kilometers. That’s far enough to reach Hawaii, Alaska, and parts of the continental United States.

It’s paired with the DF-17 and DF-26, which are road-mobile systems that can swap nuclear and conventional warheads on short notice. The DIA projects China will field 4,000 aeroballistic and glide-vehicle hypersonic weapons by 2035.

These aren’t slow-moving Cold War relics.

They’re specifically engineered to slip past legacy defenses like Patriot and THAAD by maneuvering mid-flight at speeds up to Mach 10.

Add a submarine-launched missile with intercontinental reach to that mix, and the “homeland as sanctuary” assumption the U.S. has operated under for 70 years starts to look outdated.

China Isn’t Alone

Russia has spent the past several years bombarding Ukraine with advanced missiles, including hypersonic variants like the Kinzhal.

Just this week, Russia hit Kyiv with 29 ballistic missiles overnight. Ukraine’s air defenses — built on years of Western Patriot batteries, NASAMS, and IRIS-T — intercepted zero of them.

Not because the hardware failed. Because volume beat point defense.

That’s the lesson for U.S. planners. A single layer of ground-based interceptors doesn’t hold up against a determined, high-volume adversary. 

Iran made a similar point this spring. And if Russia and China have advanced, long-range hypersonic missiles, it’s only a matter of time before Iran does too. 

That means the next time we have a military conflict with Iran, it might not just be confined to the Middle East.

The Golden Dome Isn’t Optional

This is exactly the scenario Golden Dome is designed to address.

It’s not a single radar site or interceptor battery, but rather a full “system of systems” — proliferated satellites that track a missile from the moment it launches, space-based interceptors that can kill it in boost or midcourse, and a command layer tying it all together before ground defenses ever have to fire.

Congress has already committed $17.9 billion to the program, on top of $24.4 billion allocated the year before.

The Space Force has handed out $3.2 billion in contracts to a dozen companies building the space-based interceptor layer, with initial capability targeted for 2028.

Lockheed Martin (NYSE: LMT) is opening its first dedicated Next Generation Interceptor production plant this year. It says it will quadruple THAAD output and triple PAC-3 production.

But Lockheed and the other primes are already priced for this trade. Every fund manager on Wall Street has that one figured out.

Which is why the real opportunity sits with the smaller contractors building the sensor fusion and AI-driven targeting software that actually makes a “system of systems” work.

I’ve been tracking one in particular — a small, under-the-radar company whose signal-intelligence and AI tech is quietly getting built into the same missile-tracking architecture the Space Force just funded.

China just fired a warning shot. Russia’s already proven what happens when a defense gets overwhelmed. I’d recommend getting positioned before the rest of Wall Street catches up — start here with my full research.

Fight on,
