The essential role of cleanrooms in the aerospace and defense industry

Sophistication and strict requirements in the aerospace – defense industry

In the fields of aerospace and defense, performance, precision, and reliability are non-negotiable factors. From manufacturing guided missile systems, modern weapon modules to assembling satellites, even the smallest detail can decide the success or failure of a project. That is why cleanrooms have become indispensable environments to protect equipment from contamination risks, static discharge, or environmental impacts that can reduce the accuracy and performance of sophisticated components.

Why use cleanrooms in this special sector

• Production in a dust- and contaminant-free environment: Dust and contaminants can cause defects or reduce reliability — which is especially dangerous with ultra-small components such as guided missiles, drones, or space equipment.

• Preparation of strongly bonded surfaces: Materials such as adhesives and coatings require a clean and stable environment to achieve optimal adhesion and structure.

• Research in sterile environments: Materials can be affected by mechanical load and temperature during launch and orbit; exposure to contaminants can cause adverse effects.

• Assembly in uncontaminated environments: Equipment in harsh environments or vacuum cannot fail, as even minor contamination could lead to catastrophe.

Outstanding technical features of cleanrooms

• Advanced air filtration: Using HEPA and ULPA filters can remove dust particles as small as 0.3 µm, meeting the strict standards of the aerospace and defense sectors.

• Strict standards compliance: Aerospace and defense organizations must comply with ISO 14644 air cleanliness standards, even planetary protection protocols of NASA; while the military must apply strict quality standards and regulations.

• Comprehensive environmental control: Parameters such as temperature, humidity, pressure, and airflow are strictly controlled to ensure stability and precision in handling sensitive components.

• Antistatic floors and vibration-free environments: Help minimize electronic damage risks; a quiet environment is required for delicate optical assemblies.

Customized design according to needs

• Customized cleanrooms: Many cleanrooms can be connected, integrating special features such as sliding doors, control panels, glove ports, or pass-through chambers to meet requirements for cleanliness (ISO), Class A fire protection, ESD antistatic criteria, etc.

• Mobile and easy assembly: Some cleanrooms can be installed, dismantled, moved, and reassembled at different sites — very flexible.

Notable examples

• James Webb Space Telescope — uses an octagonal Airblock Softwall cleanroom to surround the rocket nose cone, protecting the high-altitude infrared mirror before launch.

• Iron Dome Laser System — includes an ISO Class 6 cleanroom with 3 airlocks, dedicated changing room, high-speed roller doors, and seismic-rated earthquake-resistant structure.

• Cleanroom on satellite support gantry — built on a transparent Polysim frame bridge, integrating exhaust fans and HEPA filters to clean as technicians cross the bridge into the rocket nose.

Future trends

• Demand for even cleaner environments: As technologies like quantum computing in defense or deep space missions develop, cleanroom requirements are becoming more urgent.

• Increased automation and robotics: To reduce contamination from humans, assembly and testing procedures are increasingly shifting to robots to achieve unprecedented cleanliness levels.

Anh Khang's perspective

In the aerospace and defense industry, cleanrooms play an irreplaceable role in protecting sophisticated equipment from contamination and loss of reliability. From standard design to customization for each mission, from building telescopes to defense laser systems, cleanrooms are the foundation for ensuring success and safety. As the industry raises cleanliness standards, cleanrooms continue to evolve—moving toward a future with more automation and environmental control than ever before.
