Stealth Bombers and Bunker Busters

by | Dec 4, 2025

A retrospective analysis of the so-called 12-Day War, and the triumphantly celebrated Operation Midnight Hammer.

The GBU-57 is a big fat gravity bomb with fins. To achieve effective precision, a B-2 bomber must drop it on its intended target from no further than about five nautical miles — essentially right on top of the target.

Its penetration depth is claimed to be 200 feet. But that capability has NEVER been tested against a seriously hardened deep-underground target encased in layers of high-performance concrete, and topped with a few dozen meters of solid rock. In that sort of real-world scenario, the GBU-57 would be lucky to drill down 50 feet, if that.

It was always ridiculous silly talk to suggest the GBU-57 was the wonder weapon it was made out to be. There is a good reason the US only produced a couple dozen of them and then stopped: they understood its acute limitations in a non-permissive combat environment.

And, notwithstanding the hyperbolic Israeli propaganda, there was never any credible evidence that Iranian medium- and long-range air defenses against fixed-wing aircraft were attrited to any significant degree. And Iranian short-range air defenses were increasingly effective against long-range Israeli drones with each passing day.

As for the B-2: it is a big fat subsonic aircraft. It flies at airliner speeds. A strike on Fordow would entail flying at least 500 miles in and out of Iran.

It is nonsense that the B-2 is effectively invisible. It can be tracked from long distances, and targeted sufficiently well that missiles with effective terminal guidance (thermal / optical) can kill it.

The Iranians established during the October 26, 2024 Israeli counterstrike that they could paint F-35s with their radars. That is why the Israelis launched nothing but long-range stand-off munitions: aero-ballistic and cruise missiles – of which they have a very limited stockpile.

The same conditions prevailed during the 12-Day War.

And just as the Israelis were unwilling to risk getting fighters shot down over Iran, neither was the USAF willing to risk getting a B-2 shot down over Iran.

Maybe a few B-2s launched some JASSMs from over Iraq or the Caspian Sea. Maybe nothing but sub-launched Tomahawks hit Iranian targets. But it certainly wasn’t GBU-57 “Bunker Buster” bombs dropped by a half-dozen B-2s casually flying in Iranian airspace for an hour.

And whatever was dropped inflicted no meaningful damage. Fordow was scratched at best. A bunch of surface structures at Natanz were blown up.

Trump’s claim that Iran’s nuclear program was destroyed is absurd nonsense. No one with even a modest understanding of these things believes that.

The Israelis certainly don’t believe it, and they have admitted as much.

It is true that, in retaliation, the Iranians precisely targeted and convincingly destroyed a significant communications complex at the American Al Udeid airbase in Qatar.

The fictionalized B-2 “Bunker Buster” strike on Fordow, and the token Iranian ballistic missile strike on Al Udeid were orchestrated events designed to grease the tracks of a ceasefire that was proposed by the Americans and agreed to by the Iranians.

The Americans and Israelis had expended almost their entire inventories of ballistic missile interceptors over the course of a week and a half, and Iranian missiles were raining down with effective impunity the last few days.

The Iranians knew damn well they had already achieved a strategic victory, despite their shaky start.

I’m also convinced the Russians and Chinese encouraged Iran to accept the ceasefire proposal.

It allowed both sides to claim a PR victory, lick their wounds, and prepare for the next round.

Meanwhile, the Iranians have more production capability than do their US/Israeli counterparts. And it also appears the Iranians are much more amenable to Russian and Chinese assistance now than they may have been previously.

When this war resumes, the Iranians will be comparatively stronger than they were before. And the risks for the US/Israel will be significantly heightened.
