The B-21 Raider, being a newer generation of stealth bomber, incorporates several advanced technologies that were not present in the original design of the B-2 Spirit.

Here are some key examples:

Advanced Stealth Capabilities:
- Newer Composite Materials: The B-21 utilizes advanced composite materials that are inherently stealthy, complemented by an embedded, thinner, and multifunctional Radar-Absorbing Material (RAM) coating.
- All-Aspect Low Observability: The B-21's design achieves low observability across a wider range of the electromagnetic spectrum, including radar, infrared, and acoustic, making it harder to detect from multiple angles.
- Improved Engine Masking: The B-21 features more tightly masked engine inlets and fully shielded exhaust, significantly reducing both radar and infrared signatures.
- Self-Healing Stealth Coating: The B-21 is equipped with a self-healing stealth coating that can potentially repair minor damage, reducing the need for extensive maintenance after every mission, unlike the B-2.
Advanced Avionics and AI:
- Modular Open Systems Architecture: The B-21 is designed with a modular, open systems architecture, allowing for easier upgrades to its software and hardware to counter evolving threats.
- AI-Assisted Design: High-fidelity computational electromagnetic (CEM) modeling and AI-assisted optimization were used in the B-21's design, ensuring optimal placement of components for reduced signature across multiple spectrums.
- Potential for Autonomous Operation: The B-21 has the potential to operate without a pilot, either being remotely controlled or employing artificial intelligence for tasks like threat assessment, route adjustments, and munition deployment.
Operational Flexibility:
- Potential for Optional Manned/Unmanned Missions: The B-21 is designed to be optionally manned, offering greater operational flexibility.
- Wider Range of Weapons: The B-21 can be integrated with a wider array of future weapon systems, including hypersonic missiles.
- Increased Range: The B-21 boasts a longer range than the B-2, enabling it to strike targets deep behind enemy lines.
- Designed for Contested Environments: The B-21 is specifically engineered to operate and survive in high-threat, contested airspace.

It's important to note that many specific details regarding the B-21's technology are classified, so some information is based on public statements and expert analysis.
