On January 13, 2020, the Ministry of Defence announces new fuel upgradation for Indian Navy with revised technical specifications. The High Flash High Speed Diesel (HFHSD) was launched. The aim of the new fuel introduction is to reduce carbon footprint.
Indian Navy, one of the largest navies in the world in collaboration with Indian Oil Corporation carried out several trials before concluding on HFHSD. The Joint Collaboration studied the international regulations of MARPOL, NATO, ISO before concluding on the revised technical specification. Around 22 test parameters were considered. This included certain critical parameters such as flash point, cetane number, sediment content, sulphur content, cold filter plugging point and oxidation stability.
The upgrading of fuel is essential in order to keep pace with new technologies and emission standards. This will also help other IOC customers and merchant mariners in the following years. It will also benefit foreign Navy ships participating in exercises.
Bottom line, the fuel upgradation will help in reducing carbon footprint, equipment reliability, increased performance and will help Navy achieve its Mission based deployment.
Critical Parameters of HFHSD
- Flash Point-Flash Point of the lowest temperature at which HFHSD can form an ignitable mixture with air. Lower the flash point, easier is the ignition. The Flash Point of HFHSD is 66.
- Cetane Number-It is the number with which the performance of the fuel is measured. Higher the number, better is the fuel performance. The Cetane number of HFHSD is 45.
- Cold Filter Plugging Point-the temperature at which the fuel passes through the standardised filtration device. The Cold filter Plugging Point is yet to be updated in the report.
- Cold Filter Plugging Point-The lowest temperature at which the fuel passes through standardised filtration device.
- Sulphur Content-the percentage of Sulphur (by mass) present in HFHSD. The Sulphur Content of HFHSD is 0.2%

The Government of India will acquire around 200 aircrafts. Of these 200, 83 fighter jets are LCA Tejas Mark 1A and are to be procured from HAL. The rest are to be procured based on Request for Proposals.
The design of the fighter jets was finalized by HAL (Hindustan Aeronautics Limited). HAL will start manufacturing 8 LCA (Light Combat Aircraft) Tejas Mark 1A per year and will slowly increase the count to 16 per year. The LCA Tejas recently became the first indigenously made aircraft to make arrested landing on INS Vikramaditya.
The LCA Tejas was designed by HAL (Hindustan Aeronautics Limited) and ADA (Aeronautical Development Agency) in 1980s. It replaced India’s MiG-21. So far, LCA Tejas is operating only in India. However, Egypt and Sri Lanka have shown interests in the aircraft. This will help India achieve its Defence exports targets of Rs 35,000 crores by 2024.
India has plans exports Tejas Mark 1A and not its advanced version Tejas Mark 2.
Tejas Mark 2
Tejas Mark 2 has increased internal fuel capacity of 3.3 tonnes. Also, it is equipped with an artificial intelligence-based cock pit that is optimally manned. It has provisions for the ground stations to take control when the pilot falls unconscious or is injured. The alert signals of unconsciousness of the pilot will be generated by his helmet.
