The Box MLRS Revolution

The BM-30 Smerch remains a fearsome weapon. It’s often compared and not unreasonably to the M270 MLRS on the opposite side of the Berlin Wall. But in many ways, it’s like the last generation of propeller aircraft, while the MLRS was one of the first jets. And I’m not talking about guided rounds.

One of the biggest differences is that the Smerch has to be manually reloaded one rocket at a time. The MLRS/HIMARS just involves plopping in a new canister full of rounds (and the launch vehicle itself has a crane to boot). Many other newer systems (primarily Chinese, Israeli, and Turkish) also use the canister system, even if some still need the extra expense and risk of a separate loading vehicle.

Though too little and late for the current war, the Russians did eventually go for the box MRL with the Tornado series. However, I’m earnestly baffled why they didn’t try to do so more while the USSR was still intact, given the obvious advantages of such a system. Sunk costs of existing rockets and later post-1991 financial troubles are a possibility. Or maybe it was because the Smerch’s giant rockets couldn’t be canisterized. But still, given the prominence of artillery, and the use of other mechanical aids (automated naval vessels, autoloaders for tanks), it still is a little surprising.

Clustering launchers for fun and profit

You are a rogue state with limited resources, and you want to make more powerful rockets. What is your improvised expedient? The answer, be it in North Korea or (with the most documentation) in Saddam’s Iraq, is frequently to cluster existing engines.

And what kind of engines would they be? There are the ubiqutuous Scud derivatives, but there’s also something even more readily available-surface to air missile engines, especially those (ie, SA-2s) becoming ever-less effective against actual opposing planes. Iraqi rocket/missile designs made extensive use of repurposed Guideline engines.

It’s gotten to the point where I’ve been making (oversimplified, of course) hypotheticals using the launcher and ballistic missile online calculators. Just input the relevant characteristics, thrust and size dimensions for the engines/rockets in question, and see the result! Quite an interesting bit of diversion for me.

The Monster Rocket

I give you the Type 762 rocket launcher, a fairly old and obscure Chinese self-propelled artillery piece. This is well, if you combined a FROG, a TOS-1, and a Giant Viper all into one platform, you’d get this.

From its stated (as always, take with a grain of salt) statistics, it has a pair of very short range (around only a kilometer!) thermobaric rockets (like the TOS-1), that are huge at 425mm diameter (only somewhat thinner than the FROGs) and which are primarily meant for clearing minefields (like the Giant Viper). Although with a rocket that big, I’m guessing that it’ll “clear” more than just land mines in the area it hits.

Truly an oddball.
