posted from the link given by Cobra commando - This is one of the major achievment of DRDO.Hence highlighting the post.

A 1000 kg glide bomb designed and developed by Defence Research and Development Organisation (DRDO) was successfully tested today, in Bay of Bengal of the coast of Odisha. The bomb was dropped by an Indian Air force aircraft, The bomb, guided by its 'on board navigation system' glided for nearly 100 km before hitting the target with great precision. The flight of the glide bomb was monitored by radars and electro-optic systems stationed at Integrated Test Range (ITR). Multiple DRDO laboratories namely, DARE, Bangalore, ARDE, Pune and TBRL, Chandigarh, with RCI, Hyderabad as the nodal laboratory have contributed towards development of the glide bomb. The complete avionics package and navigation system has been designed and developed by RCI.

Dr. Avinash Chander, Scientific Advisor to RM, Secretary, Deptt. of Def. R&D & DG DRDO has congratulated all the team members including the Air force team who have contributed in the success and stated, " The nation today has capability to design, developed and launch heavy bombs for delivery up to 100 km away with high precision". Dr. G Satheesh Reddy, Distinguish Scientist and Director RCI stated, "Country has now become self-reliant in the area of guided precision bombs".

I may not be expert on munitions but I do have a query on the 100 km range.

Assuming this is a dropped munition from a aircraft. say it is dropped at a height of 10 km altitude , report says it can travel 100 kms with guided precision. We are talking about horizontal movement of 10km for every km of drop. I.e 10mt horizontal movement for every 1mt drop, which is more than 45deg angle of horizontal movement. I don't recall seeing any PGM having more than half a meter wingspan.

Appreciated somebody can clarify if my thought process is wrong!!!

Add the velocity at which glide bomb is released from aircraft. Even more than 100 km is possible, just increase the release velocity.

Have you ever played paper plane game?? at what height you used to release the planes and what range they covered, even if you release in horizontal plane it will cover more than 5 times than released altitude in normal conditions, now image at what speed an aircraft releases the missiles and bombs, usually >400 kmph.

India Successfully Tests One Ton Glide Bomb. Why That's Important

The precision-guided bomb, tested in the Bay of Bengal off the coast of Odisha, was dropped by an Indian Air Force aircraft.The bomb, guided by its on board navigation system, glided for nearly 100 km before hitting the target with "great precision," said the Defence Research and Development Organisation (DRDO), which constructed it.

Several radars tracked the flight of the bomb which was developed by multiple centres linked to DRDO.According to Dr G Satheesh Reddy, the Director of the DRDO's Research Centre Imarat Laboratory which was the nodal agency in developing the glide bomb, "India has now become self-reliant in the area of guided precision bombs."

Unlike missiles, glide bombs have no onboard motor and are therefore far cheaper to build and maintain than missiles. Glide bombs rely on small control surfaces which direct the weapon towards a target as it progressively loses altitude after being released from an aircraft. The key to a precision guided bomb is its seeker which can lock onto a target based on pre-programmed targeting data. The seeker itself can be optical, infrared or a combination of the two and telemetry for the bomb can also be provided from overhead satellites.

With a range of 100 kms, the Indian-built glide bomb can be fired on ground targets which are beyond the range of most surface-to-air missile systems in use in Pakistan and China. In other words, the pilot of the fighter dropping the bomb can drop the weapon and escape before entering the range of the radars of enemy surface-to-air missiles which can shoot it down.

No images of the DRDO-developed glide bomb have been released so far

Add the velocity at which glide bomb detached from aircraft. Even more than 100 km is possible, just increase the release velocity.

Speed of the aircraft and altitude plays a huge role in Range. Its very similar to Air to Air missile.For example Astra missile range is 115Kms when shooted at 11Km attitude and 0.9 mach. Its range reduces to just 44kms when shot over 5 kms.

Yes both altitude and velocity of release plays an important role in range.

Yup point taken, trying to dig up physics formulas on free falling objects. so that once and for all i can convince myself. It has been some decades since i used any physics formulas.

Manpower

8. The Committee note that at present 7809 number of scientists (including Service Officers and Work Officers) are working in
Defence Research and Development Organisation (DRDO) against the sanctioned strength of 7932 (including 7255 Scientists, 623 Service Officers an
d 54 Work Officers) (as per Govt. Orders in 2001)

The Committee also note that while the number of projects have grown multi-fold in terms of size and technological complexity keeping in view India's strategic and tactical defence requirements but there has been no increase of scientific manpower in DRDO since 2001. The Committee feel that scientific manpower in DRDO should commensurate with the R&D requirements and projects undertaken. As intimated by the Ministry that a cabinet note for augmentation of additional posts of scientists had already been forwarded for consideration of the Government. The Committee desire that the matter may be pursued vigorously at the highest level and they are apprised of the same within three months of presentation of this report.

9. The Committee also observe that on an average of more than 65 scientists have been resigning from DRDO since 2009. Till 1st October, 2014, 23 scientists have left the organisation. The reasons given for their exodus are indicated as their personal/domestic grounds. However, the Committee opine that conducive
work environment, invigorated growth opportunities and suitable incentives can 46 control such resignations. The Committee would like to be informed about the
steps taken in this regard by the Ministry.

Performance audit of the work of scientists of DRDO
10. The Committee have also observed that there are many projects, undertaken in different DRDO labs, which are not attaining completion due to shortage of manpower. The Committee desire that all out efforts should be made by DRDO to ensure that projects undertaken by it are not delayed on account of shortage of manpower.

validation as per International Maritime Organisation Standard Test Protocol, design guidelines for a
Water Mist System for onboard fire protection in engine rooms of ships will be developed for use by
Indian Navy. The fabrication of simulation chamber with twin-fluid water mist system and instrumentation
is under progress.
Wireless Instant Fire Detection and Suppressions System for Armoured Fighting Vehicles
Fire Detection and Suppression System (FDSS) for Armoured Fighting Vehicles (AFVs) has been
developed, which caters for any eventuality of fire inside the crew and engine/transmission compartment
of battle tank. This system can detect, fight and totally suppress fire within 150 ms, thereby enhancing
crew and vehicle survivability and safety. The system is in production after successful performance
during user trials. Further work is in progress to develop state-of-the-art micro-controller-based FDSS.
