B‑21 Raider Moves Forward: Key Progress

Northrop Grumman has delivered a second B‑21 Raider flight test aircraft to Edwards Air Force Base. The addition of this second aircraft significantly boosts the flight test campaign.

The testing is now moving beyond basic flight performance — the focus is shifting to mission systems and weapons integration, which are critical for future operational capability.

Ground test efforts continue in parallel. Engineers are subjecting the Raider to extreme mission condition simulations and durability testing (e.g. simulated lifetimes), and so far it’s been performing better than earlier digital models predicted.

Support, Sustainment, & Upgrades

Northrop Grumman is developing an enhanced software package aimed at enabling the B‑21 fleet to receive seamless updates—ensuring that the aircraft’s mission capabilities and weapons systems can evolve to meet future threats.

For training and maintenance, the company is putting in place full‑scale support systems: simulators, immersive labs, virtual environments, and a Fleet Management Tool for maintenance and sustainment. This infrastructure is designed so that when B‑21s are deployed, squadron crews, maintainers, and support personnel are ready.

Bigger Picture & Strategic Implications

The expansion of testing with more aircraft accelerates the path toward operational readiness. Having more test assets allows for faster validation of systems, weapons, and mission performance.

The B‑21 is being positioned as a cornerstone of the U.S. long‑range strike capability, incorporating both nuclear and conventional roles.

Air Force to Field Autonomous Cessna Caravan

The U.S. Air Force has taken a significant step toward transforming airlift operations with a $17.4 million contract awarded to Reliable Robotics for its aircraft autonomy system, the Reliable Autonomy System (RAS), to be deployed on Cessna 208B Grand Caravan single-engine turboprops.

Why This Matters for the AFA and the Air Force Community:

  • End-to-end automated flight: RAS enables automated taxiing, takeoff, flight, and landing—offering robust autonomy with built-in redundancy and precision navigation that addresses common safety risks like controlled flight into terrain (CFIT) and loss of control in flight (LOC‑I).
  • Designed for austere environments: The Indo‑Pacific region is set to benefit first, with the aircraft’s simplicity and autonomy enabling efficient missions in remote areas where human resources are stretched.
  • Safety + affordability: With a much lower operational cost—approximately $2,000 per flight hour compared to around $20,000 for a C‑130J—and a 90% dispatch reliability rate, the Caravan proves to be both cost-effective and ready for rugged service.
  • Multi-platform potential: Though the Caravan is the immediate focus, RAS is aircraft-agnostic. The Air Force is already exploring its integration with larger models like the KC‑135 Stratotanker and Cessna 408 SkyCourier.
  • Proven performance in exercises: Reliable Robotics previously demonstrated RAS capabilities during real-world, military‑style Agile Flag exercises—autonomously flying Caravan missions across multiple California and Nevada airfields via remote pilot operations with an onboard safety pilot.

What’s Next? This contract marks a pivotal milestone in the Air Force’s shift toward autonomous aviation. By leveraging commercial-grade autonomy solutions like RAS, the service is poised to enhance operational readiness, cost efficiency, and mission adaptability, especially within the doctrine of Agile Combat Employment.

Air Force Names OA-1K Skyraider II

February 27 2025… About a month away from its arrival, the Air Force named an upcoming light attack and observation aircraft after an iconic Cold War-era close air support platform.

The OA-1K—from the Armed Overwatch program—will be called the Skyraider II, Air Force Special Operations Command officials said. The modified cropduster will provide airborne eyes, ears, and precision fires to support ground troops in permissive airspace, just as its namesake, the A-1 Skyraider, did in the Korean and Vietnam Wars. (Read the full story here at Air&Space Forces Magazine)
