The Oerlikon GDF Anti-Aircraft System: a Towed Twin 35 mm Cannon
Developed by the Swiss company Oerlikon Contraves, the Oerlikon GDF is a towed anti-aircraft artillery piece designed to protect areas and fixed assets. Its primary mission is to intercept low-flying aircraft and cruise missiles, creating a dense defensive barrier. When prepared for operation, its dimensions are considerable, reaching 7.8 meters in length, 4.5 in width, and 2.5 in height. To mobilize it, a towing vehicle is needed to pull its four-wheeled trailer. 🎯
Firepower: the KDA Automatic Cannons
The heart of the system consists of two Oerlikon KDA 35 mm automatic cannons, installed side by side. These can employ programmable AHEAD ammunition, an advanced type of projectile configured to detonate in front of the target. Upon exploding, it releases a dense cloud of tungsten subprojectiles, dramatically increasing the probability of hitting the target. The combined firing rate of both weapons is extremely high, allowing to saturate a volume of airspace with a curtain of metal. 💥
Key armament features:- Twin 35 mm KDA cannon: Fires in parallel with a very high combined firing rate.
- AHEAD ammunition: Programmable projectiles that burst before impact, dispersing subprojectiles.
- Area defense: Capability to create a lethal denial zone against aerial threats.
Modeling the Oerlikon GDF in 3D requires capturing its iconic silhouette: two long parallel cannons on a compact and functional trailer chassis.
Guide to Modeling the GDF in 3D
When creating a digital model of this system, it is essential to accurately represent its classic and characteristic profile. The two long parallel cannons, along with the compact shape of the trailer, define its aesthetics. To achieve a high level of detail, components such as the hydraulic stabilizers, seats for the crew, and large ammunition containers mounted on each side of the cannon can be included. A complete scene can separately integrate the Skyguard guidance radar, which, although not a physical part of the GDF, usually works in conjunction with it to detect and track targets. 📐
Essential details for the 3D modeler:- Profile and proportions: Focus on the silhouette with the parallel cannons and the trailer body.
- Detailed components: Model stabilizers, seats, and side ammunition containers.
- Contextual element: Consider modeling the Skyguard radar to complement the scene.
- Wheels and deployment: The wheels must be able to rotate for transport and lock/raise slightly in firing position, transferring the weight to the stabilizers.
Conclusion for Digital Artists
The Oerlikon GDF presents an interesting challenge for 3D modeling, combining complex mechanics with a recognizable shape. Paying attention to the details of its operational deployment, especially the state of the wheels and stabilizers, adds realism and authenticity to the project. Representing this system not only involves capturing its appearance but also understanding its function as a key piece of anti-aircraft defense. 🛡️
