Introduction to Stealth Technology
• Stealth Technology or Low Observable Technology (LO technology) is a sub- discipline of military tactics and passive electronic countermeasures.
• It cover a range of techniques used with personnel, aircraft, ships, submarines, missiles and satellites to make them less visible (ideally invisible) to radar, infrared, sonar and other detection methods.

Stealth Technology in Naval Warfare
• Stealth Technology finds its extensive application in the Naval Domain also as many ships and submarines are designed and fabricated as per the technology.
• It uses design, material and advanced technology to ensure that a warship or submarine avoids detection by electronic systems. A stealth ship or submarine aims at becoming invisible to Radar, Sonar and Infrared systems.

Principle and Working
Principle:
Stealth technology is not a single technology but a combination of technologies that attempt to greatly reduce the distances at which a vehicle can be detected; in particular radar cross section reductions, but also acoustic, thermal, and other aspects.
Stealth technology works on the principle of eliminating radar reflections. This can be done by either:
• Deflecting Radio Waves (Shaping of the surfaces)
• Absorbing Radio Waves (RAM coatings)

Principle and Working
Radar cross-section (RCS) reductions are achieved by :
• Vehicle Shape and Design
The shape and design are such that they deflect the incoming radio waves due to their clean yet angular design. The radio waves get deflected due to the presence of angled physical elements.

Principle and Working
Radar cross-section (RCS) reductions are achieved by :
• Material
Radar-absorbing material (RAM), often as paints, are used especially on the edges of metal surfaces they absorb radiated energy from a radar station into the coating and convert it to heat rather than reflect it back. Current technologies include dielectric composites and metal fibers containing ferrite isotopes. A commonly used material is known as “Iron Ball Paint”.

The clean and angular design of deflects the incoming radio signals.

The RAM coating along with the surface texture absorbs and converts incoming radiations into heat energy.
Advantages
• Ships and Submarines using Stealth Technology are almost undetectable by RADAR.
• They can be used for secret missions due to their unmatched ability to disguise the radio waves.
• Since they aren't noticeable, they ensure relatively better safety of the pilot and crew as compared to the ships and submarines using conventional technology.

Current Use
• Currently many countries including: USA, UK, France, Sweden, India etc. are using Stealth Ships and submarines.
• Stealth Ships and submarines are generally used for patrolling and spying purposes of disputed waters.
• Due to their inability to carry relatively less payload, they somewhat are less suitable for direct combat instead of that they are unchallengeable when it comes to launch a surprise attack.

Future
• Improvement in designs are in progress as the ships and submarines become detectable when they open the weapon bay.
• Different countries are working on prototypes of ships and submarines with improved payload.
• Development of advanced RADAR absorbing materials (RAM) is in progress.

Conclusion
Stealth technology is an interesting and topic and as much of the research and technology development done in this area is secretive, it is impossible to know exactly what sort of new advances lie in the future. The stealth technology has gone as far as it could go but the fact still lie that all stealth aircraft are vulnerable to existing and futuristic counter-stealth technologies.
