BEHIND THE SCENES - Tulip Flames: The 2S4 Tyulpan - A Tribute to Cold War Engineering

The Beast of the Battlefield: Why the 2S4 Tyulpan Matters

In the shadowed corridors of Cold War history, the 2S4 Tyulpan stands as a paradox—a weapon of brutal efficiency wrapped in the poetic nickname “Tulip.” Designed in the 1970s as a response to NATO’s fortified bunkers, this self-propelled mortar was engineered to obliterate hardened targets with 240mm shells capable of piercing 12 meters of concrete. Unlike its contemporaries, the Tyulpan didn’t just bombard; it excavated. Nicknamed the “Bunker Buster” by Soviet troops, it became the scalpel in the USSR’s arsenal, carving through obstacles that lesser weapons merely scratched.

For military enthusiasts, the Tyulpan represents a watershed moment in artillery design. Its hybrid chassis—a marriage of a GMZ mine-laying vehicle and a turret housing the colossal mortar—allowed it to fire, reposition, and vanish before counter-battery radars could lock on. “It wasn’t just a weapon,” says Yestin Fun, NifeliZ’s lead designer. “It was a chess piece in the Cold War’s deadliest game.”

The Designer’s Vision: Merging Form and Function

Yestin Fun’s obsession began with a single photograph: a Tyulpan poised in the Afghan mountains, its barrel angled like a violinist’s bow. “I wanted to capture that tension between elegance and destruction,” he recalls. But translating a 27-ton behemoth into a building brick set demanded more than reverence—it required engineering alchemy.

Challenge 1: The Barrel’s Ballet
The Tyulpan’s 20-foot barrel could elevate to 80 degrees, a feat Yestin replicated using a dual-axis hinge system. “We tested 14 prototypes,” he admits. “Traditional LEGO hinges sagged under the weight, so we combined Technic liftarms with custom brackets. Now, when you adjust the barrel, it clicks into place like the original’s hydraulic locks.”

Challenge 2: The Baseplate Paradox
The mortar’s baseplate—a 1.5-ton steel disc—had to absorb recoil without toppling the model. Yestin’s solution? A collapsible brick lattice inspired by origami. “It unfolds like a flower,” he says, “but locks rigid under tension. Builders will feel that ‘snap’ of stability—the same sensation crews felt when deploying the real Tyulpan.”

A Model That Tells a Story

Open the NifeliZ Tyulpan’s hull, and you’ll find secrets even historians might miss: 
The Ammo Bay’s “Easter Egg”: Slide out the brick-built 3OF-3 shells, and you’ll find tiny Cyrillic markings—a nod to factory stamps on original munitions.

The Cockpit’s Cold War Quirks: The driver’s periscope uses a transparent orange brick to mimic Soviet anti-laser filters. “It’s pointless in a model,” Yestin laughs, “but it’s those details that whisper, ‘This was built by humans, not machines.’”

A Tribute to Innovation

For Yestin, the Tyulpan’s legacy isn’t measured in rubble but in risks taken. “The Soviets could’ve built another tank,” he notes. “Instead, they created this thing—a mortar that thinks it’s a missile. That’s the spirit we channeled.”
