the transformation of the cost and technical difficulties

pment stupid big famous, a few decades ago the old equipment on the aircraft is super big elephant in general occupy a great space, the weight is considerable.
Removed the old electronic systems installed on new products, electronic systems with each passing day, ten times before you can achieve before the tenth volume function, so the small cockpit which can be more devices.
In fact, the transformation of these old aircraft as early as in the 1980s began to study Chinese-made unmanned drone technology in the world, leading.
However, cost-effective than the transformation of large areas of old aircraft is a topic of debate, the transformation of the cost and technical difficulties; worry about the interference of the stand strong electronic interference and modern smokescreen for weapons; fear of combat accuracy is not enough, adversely affected by aircraft has been plagued by the experts, so can only do some small amount of transformation test has been large quantities of modified plans have already been shelved.
nfl to bring the technology can solve many problems, the new coating can absorb radar waves can maximize hide their old aircraft, the new airborne equipment is equipped with the Beidou navigation system, anti-electronic jamming systems, remote control automatic digital electronic systems, if necessary, can also be put on a new aircraft engine, this will effectively increase the combat radius, the installation of air to air or ground missiles, air-to-ship missile, can be done completely over-the-ho
