Summary

The HAL Advanced Medium Combat Aircraft (AMCA) is a fifth-generation fighter aircraft. It is being developed by an aerospace industry team which consists of the Aeronautical Development Agency as the design firm with manufacturing carried out by Hindustan Aeronautics Limited (HAL) as the primary contractor and main assembly firm. Went into development 2008. The Indian Navy will also be seeking a naval variant optimized for operation from their aircraft carriers.Expected first flight is to occur in 2024.

It is a multirole combat aircraft, a single-seat, twin-engine, stealth super-maneuverable all weather condition. Designed for the air superiority, ground attack, bombing, intercepting, strike. It combines supercruise,stealth, advanced AESA radar, supermaneuverability, and advanced avionics to overcome and suppress previous generation fighter aircraft along with many ground and maritime defenses. It is meant to be the competitor of the JSF (F-35) and set to replace the Migs and Mirage fighter Jets.

Summary

The following is the link providing in detail of the 

project :http://en.wikipedia.org/wiki/Boeing_X-51

The X-51A is an unmanned scram-jet demonstration aircraft for hyper-sonic flight testing. the airforce has been in development of a hyper-sonic propulsion device since the 1990's. Only recently it has reached the stage of flight testing due to advancement in technology. First successful flight was in 26th May 2010. On 1st May 2013 the aircraft flew for 300 sec in hyper-sonic speed. The X-51A uses shockwaves to add lift and speed. The technology will be used to provide applications in High Speed Missiles, Hyper-sonic Travel & Space Travel.

Why was this Project Canceled?

The following is the link in detail of project & why it was canceled: http://en.wikipedia.org/wiki/Boeing_2707

Summary of reasons why it was canceled:

• Environmental Concerns - opposition to such project was becoming very vocal especially from the environmental lobbyist. voicing concerns over the depletion of the ozone layer due to high altitude flights, and noise concerns relating to sonic booms over residential areas.
• Govt. Funding Cut/Rising Costs - Despite strong support from the Nixon administration the senate rejected further funding. Even with public contribution of $1 Million, the project could not continue. The Vietnam war had a strong factor in this.
