Hydraulic systems are losing viability in modern military operations. Electromechanics replaces them with ±0.1 mm precision, guaranteed operation from -10°C to 50°C, silent operation below 70 dB, and predictive rather than preventive maintenance. While hydraulic cylinders need periodic oil changes and carry a contamination risk in enclosed spaces, electromechanical systems deliver absolute reliability where the margin for error is zero. That is why military infrastructure in Europe and America is electrifying presses, bunkers, stabilisation systems and tactical equipment.
Why hydraulics is no longer viable in defence
A hydraulic system in constant operation needs periodic cylinder inspection, oil changes and seal cleaning. In military infrastructure that means scheduled downtime. And when national security is at stake, any period of inactivity is a risk that is hard to justify.
The real problem is not only maintenance. Hydraulic tanks operate under pressure. In enclosed spaces, underground bunkers or structures with controlled ventilation, an oil spill contaminates the air operators breathe. It is not an administrative inconvenience. It is an operational health risk that directly affects mission continuity.
There is one more factor many military engineers know: noise. A hydraulic system produces 75-85 decibels when running. In tactical missions where every sound can reveal positions, that is a clear operational disadvantage.

What electromechanics achieves that hydraulics cannot
Electromechanics is not a generic replacement. It redefines what is possible in contexts where the margin for error is zero.
Ultra-fine precision under extreme load
Ballistic components require tolerances that civil industry rarely needs. ±0.1 millimetre precision in every batch produced. This is achieved through parametric design validated with FEM (Finite Element Method) analysis, which simulates every variable before manufacturing.
The result: absolute consistency. Component after component. Batch after batch. No deviations.
Operation across the whole temperature range
An electromechanical system delivers identical performance at -10°C as at 20°C or 50°C. There is no loss of fluidity, no change in viscosity, no seal contraction. This opens up operations that used to be limited: Arctic regions, deserts where daytime temperatures exceed 50°C, any geographic scenario.
Silent operation
An electromechanical mechanism runs below 70 decibels. A normal conversation is around 60 dB. A hydraulic system runs at 75-85 dB. The difference seems marginal. In tactical operations it is decisive: being detected or going unnoticed.
Safety in confined spaces
No pressurised tanks, no fluids that can suddenly release pressure, no spill risk in enclosed environments. Operator safety improves directly.

Real applications in military infrastructure
Manufacturing systems for ballistic components
Machines that compact and shape materials under loads of 300+ tonnes. Electromechanics allows absolute precision without variation, with FEM validation guaranteeing every machine operates within safe parameters before entering production.
Bunker doors and automatic closing systems
Smooth closing, no vibration, no unnecessary noise. Operation under any environmental condition with no pressure-related points of failure.
Ammunition loading and transport systems
Intelligent automation with granular control. If anything goes out of parameters, the system detects it and stops automatically. It reduces personnel exposure to risk.
Tactical platforms with stabilisation systems
Modern military vehicles require stabilisation that keeps aiming systems in exact position while moving over terrain. Electromechanics provides fine control under any condition.
The real cost: predictive vs preventive maintenance
A hydraulic system requires scheduled stops for preventive maintenance. That is inefficient. The electromechanical one requires predictive maintenance: sensors detect anomalies before they become failures.
The result: stops only when necessary. Less technician time. Fewer consumables. Higher operational availability.
In annualised operating cost the difference is substantial. Over 5 years, electromechanics recovers the initial investment through fewer stoppages.
FEM validation: why it matters
In defence there is no room for assumptions. Every component must meet exact parameters under extreme stress. FEM analysis simulates:
- Static and dynamic loads under real operating conditions
- Material behaviour across the -10°C to 50°C range
- Stress distribution that reveals weak points before manufacturing
- Vibrations and resonances across the whole operating range
- Cumulative fatigue in prolonged missions
This is not marketing. It is rigorous engineering that validates every machine before it enters service.
Energy independence: compatibility with renewables
Modern military systems seek independence from the grid. Electromechanics is fully compatible with renewable sources: solar panels, batteries, generators. Multiple combinations without losing any functionality.
This opens up operations in remote locations where connecting to the main grid is impossible.

Frequently asked questions about electromechanics in defence
Which military machines can be electrified?
Any machine that currently uses hydraulic cylinders for movement or pressure. Presses, loading systems, automatic doors, lifting platforms, stabilisation systems. If you have loads of 300+ tonnes and need precision, it is a candidate.
How long does electrifying an existing system take?
It depends on complexity. FEM analysis and redesign: 4-8 weeks. Component manufacturing: 6-12 weeks. Installation without interrupting operations: 2-4 weeks. The schedule adapts to your operational capacity.
Is it more expensive than keeping the current hydraulic system?
The initial investment is higher. But annual maintenance is 60-70% lower. Over 5 years, electromechanics comes out ahead. Over 10 years, the difference is substantial. We run a personalised ROI analysis for your case.
What happens if the system fails in operation?
No pressurised tanks, no sudden release of energy. No spill risk. The failure is controlled. Predictive sensors detect anomalies before a critical failure, allowing scheduled maintenance without surprises.
Can it be installed without stopping production?
Yes. Kernova plans installation using BIM modelling that avoids operational interruptions. Machines are integrated in phases, keeping critical operations running.
How do I know if my infrastructure would benefit?
If you have hydraulic machines older than 5 years, with frequent maintenance stoppages, or in spaces where noise or oil contamination is a problem, it probably would. A 2-3 week technical analysis confirms it at no cost.
