The 2S4 Tyulpan: a Russian heavy self-propelled mortar

The 2S4 Tyulpan represents a unique artillery system, with an unmistakable profile defined by its enormous main weapon. This tracked combat vehicle integrates a powerful mortar into an armored chassis, offering a fascinating challenge for digital artists. 🎯

Dimensions and visual profile

With dimensions of 8.5 meters long, 3.2 meters wide, and a similar height, its silhouette is dominated by the 240 mm M-240 mortar mounted in the rear area. To prepare for firing, the vehicle lowers a large base plate to the ground and the barrel swings backward, a mechanism that defines two very distinct visual configurations.

Key details to replicate:
  • The tracked chassis and angular armor present multiple planes and surfaces for detailing.
  • The firing system, with the base plate and pivoting tube, allows showing two postures: in transit or ready to fire.
  • The crane and external rail for loading projectiles add complexity to the model, inviting recreation of the reloading sequence.
Modeling the Tyulpan involves remembering that, despite its robust appearance, it needs several minutes to deploy and be ready to fire.

Armament and operational function

This system is designed to launch large-caliber projectiles over considerable distances. The M-240 mortar can use conventional, cluster, or guided ammunition, while the base plate absorbs the intense recoil. The crew operates from inside the vehicle, protected during movement and firing.

Armament components:
  • Main weapon: 240 mm M-240 mortar with capacity for various types of projectiles.
  • Close defense: 7.62 mm PKT machine gun to engage infantry or light targets.
  • Loading process: Performed with a crane and external rail, a mechanical detail that enriches the model's narrative.

Considerations for 3D modeling

When creating this vehicle in 3D, it is crucial to capture the transition between its two operational states. The armor texture, track details, and loading system mechanics are opportunities to add realism. Representing the vehicle during the long deployment process can convey a more authentic sense of preparation and latent power than always showing it in action. ⚙️
