What is the difference in appearance between the British Challenger 1 and Challenger 2 tanks?

<> Challenger 1 tank.

Challenger 2 tank.

The appearance differences are as follows:

The Challenger-2 still inherits the basic design and characteristics of the Challenger-1, but the turret introduces stealth technology, cancels the equipment such as the external glove box of the turret, and the vents of the advanced nuclear, biological and chemical protection system and environmental control system at the rear end of the turret are also protected by armor, so the appearance of the entire turret is very simple, which greatly reduces the radar cross-sectional area and reduces the increasingly popular millimeter-wave radar.

The probability of being seized and locked. The Challenger-2's protection capability has been greatly enhanced compared to the Challenger-1, and the most important improvement is the replacement of the second-generation Chobham composite armor jointly developed by the United Kingdom and the United States, which greatly improves the overall protection efficiency. Compared with the first generation, the second-generation Chobham composite armor adds a decayed uranium armor plate interlayer developed in the United States on the outside of the ceramic interlayer, and a Kefler lining is added inside, of which decayed uranium is the hardest metal known at present, which fundamentally improves the defect of the first generation Chobham for poor KE protection efficiency.

1 does not have a commander's perimeter sight, and 1's artillery shield is built-in, so from the front, there is a gap at the root of the barrel. 2 has the commander's circumferential sight, which is the one that stands out high, and the artillery shield of 2 is external, and there is no gap in the root of the artillery. The gun commander's sight is also mounted in different positions, 1 is mounted on the right side of the turret, and 2 is mounted directly in front of the turret, on the upper part of the barrel.

These are obvious differences.

Personally, I think the most direct difference in appearance is, of course, the fire control system, the fire control system of the Challenger 1 is very simple, and the focus of the improvement of the Challenger 2 is the fire control system, which is different from the Challenger 1, the tank turret of the 2 series has a commander's sight, and there is an obvious sight on the gun shield.

The main thing is that the armor system is different, the Challenger 2 is equipped with more and better composite armor, especially in the turret part, so the turret shape of the two is significantly different, and the gun and fire control system of the Challenger 2 have been improved, but it is not easy to see in appearance.
