Geography

If the US is foolish enough to start a big war against Iran .. geography is the indomitable god of war.

So the US is sending Carrier Strike Group One (CVN-70 USS Carl Vinson) to the Middle East, leaving CSG-5 (CVN-73 USS George Washington) to “hold the fort” in the western Pacific from the semi-safe environs of its quasi-permanent berth in Yokosuka, Japan.

All the Washington does is sail back and forth between San Diego and Yokosuka every so often to give the impression it’s doing something meaningful. Otherwise I’ve seen no indication for several years that it is anything more than a training and parade vessel.

In any case, the Vinson is headed to the Arabian Sea, and perhaps points beyond. (That remains to be seen.)

Meanwhile the deployment of CSG-8 (CVN-75 USS Trembling Puppy) has been extended, even as it remains bottled up in the northern reaches of the Red Sea, launching air strikes on Yemen from ~1000 km away, with USAF refueling tankers at the ready as needed.

The Yemeni have launched a few modest packages of antiquated drones and antiship cruise missiles in the general direction of the Trembling Puppy – all of which have been relatively easy pickings for the cruiser and destroyers and combat air patrol.

But, keep in mind, even though these old and slow Yemeni drones and missiles have little chance of scoring a hit from 1000 km away, the carrier strike group ships and planes still have to shoot at every one of them!

So every Yemeni strike package of a couple dozen missiles will deplete CSG-8’s munitions magazines by AT LEAST a corresponding number of air defense missiles, and quite possibly TWICE as many, according to standard practice of firing two interceptors at each threat.

CSG-8’s magazine depth has already been substantially depleted over the course of the past two weeks — and remember, the US Navy cannot replenish its vertical launch systems at sea.

And, of course, if military operations against Iran are the ultimate objective, then at some point the Trembling Puppy and its entourage are going to have to leave the cozy waters between Jeddah and the Gulf of Suez, and run the gauntlet of the Gate of Lamentation (Bab el-Mandeb).

That’s when things could get more interesting. Because it’s a pretty tight squeeze to pass through. A big deep-draft aircraft carrier can’t just run at full speed, zig-zagging back and forth. It has to stick to the navigable channel.

In the relatively open waters north of Jeddah, there is quite a bit of room for maneuver. But in the straits, you’re restricted to a narrow band — and most significantly, potential Yemeni missile launching sites are only ~200 km away. A more substantial strike package of 50 or so drones, antiship cruise missiles, antiship ballistic missiles, and fast boat and surface drone attacks will get there a whole lot faster, and with a much better chance of actually hitting something.

So, even though CSG-8’s odds of passing through unscathed still probably remain pretty good, there is unquestionably a considerably elevated risk compared to hiding out at the mouth of the Gulf of Suez.

But let’s suppose they sail right through the Bab el-Mandeb with minimal difficulties … then what? You join up with CSG-1 in the Arabian Sea and attempt long-distance strikes into southern Iran — strikes that would still require air-refueling to have any meaningful reach?

Because you sure as hell aren’t going to sail a couple carrier strike groups into the Persian Gulf. And anyone who believes otherwise is drowning in delusion. I mean, just look at the damn map! The Iranians have potent fire control over the passage from the Gulf of Oman, through the Strait of Hormuz, and throughout the entire Persian Gulf.

So I ask, in all seriousness, what exactly are two US Navy carrier strike groups going to do in the context of a no-holds-barred war against Iran?

To me, the entire concept screams of hubris running blindly into catastrophe.

If the US is foolish enough to start a big war against Iran, then 2025 is likely to demonstrate yet again that, combined with firepower, geography is the indomitable god of war.
