Comparison Points

1. Stealth Technology: The B-2 Spirit and F-117 Nighthawk are designed with stealth technology to reduce their radar cross-section, making them harder to detect. The B-1 Lancer has a relatively large and reflective radar cross-section.
2. Payload Capacity: The B-52 Stratofortress has the largest payload capacity among the four, while the B-1 Lancer and F-117 Nighthawk have lower payload capacities.
3. Range: The B-52 Stratofortress has the longest range, while the B-2 Spirit has a slightly longer range than the B-1 Lancer.
4. Speed: The F-117 Nighthawk and B-2 Spirit are both capable of high speeds, while the B-1 Lancer and B-52 Stratofortress have lower speeds.
5. Crew: The B-52 Stratofortress has a larger crew compared to the other three aircraft.
6. Design: The B-1 Lancer has a traditional design with a fuselage and wings, while the B-2 Spirit and F-117 Nighthawk have more angular and stealthy designs.

These differences reflect the unique requirements and design philosophies for each aircraft. The B-52 Stratofortress is an older design with a focus on heavy payload capacity and range, while the B-1 Lancer is a modern design with a focus on low-level penetration bombing. The B-2 Spirit and F-117 Nighthawk are both designed with stealth technology for high-priority missions.
