RENK and KNDS Extend Leopard 2 Transmission Contract to 2032: A €130 Million Guarantee
German powertrain maker RENK Group and tank builder KNDS Deutschland have expanded their supply contract for Leopard 2 transmissions. The extension, worth roughly €130 million, sets deliveries between 2029 and 2032.
The order covers HSWL 354 transmissions along with their TCS-354A control units and G4MA11 gear selectors. All three parts sit at the core of the Leopard 2 family’s drivetrain.
RENK announced the deal on 14 October, during the AUSA defence exhibition in Washington. Days earlier, the company had marked the start of production of its 4,000th HSWL 354 transmission at its Augsburg plant, in a symbolic ceremony attended by RENK COO Emmerich Schiller, CFO Anja Mänz-Siebje, Brigadier General Stefan Wind — head of land systems at German procurement agency BAAINBw — and RENK CEO Dr. Alexander Sagel.
The HSWL 354 is the hydrostatic-mechanical transmission fitted across every Leopard 2 sub-variant. It transfers output from the tank’s 1,500-horsepower engine to the tracks, and is widely regarded as a determining factor in both the vehicle’s road and off-road performance.
According to KNDS figures, armed forces in 23 countries operate roughly 3,300 Leopard 2 tanks and related vehicles in total. That installed base has kept RENK’s spares and overhaul pipeline consistently busy for years.
Because deliveries don’t start until 2029, the extension carries no immediate effect on near-term revenue. Market observers note that RENK shares stayed close to their 52-week low even after the announcement, suggesting investors are reading the order mainly as backlog visibility rather than a short-term earnings catalyst.
The sheer size and spread of the Leopard 2 fleet creates a steady resupply market for transmissions, engines and electronic subsystems long after new-hull production has slowed. For RENK, that translates into a predictable, long-horizon revenue stream that doesn’t hinge on fresh platform sales.
The deal is also a reminder of how dependent Europe’s land-platform supply chain is on a narrow set of critical components. New tank hulls make the headlines, but keeping an existing fleet operational for decades rests largely on suppliers like RENK sustaining output in transmissions and the wider drivetrain.
Across Europe, the Leopard 2 fleet forms the backbone of NATO land combat power. Turkey has long operated the Leopard 2A4 variant within its own armoured fleet, which makes shifts in the lead suppliers’ production and maintenance capacity an indirect but relevant indicator for long-term sustainment cost and spare-parts availability.
RENK is due to publish its nine-month results on 5 November. The company says the KNDS order will not feed directly into that report, but adds that its order book now carries visibility stretching out to 2032.
