Raytheon Develops Software-Defined Naval Radars for US Navy
Raytheon awarded contract to create software-defined naval radars enabling multi-mission capability and spectrum sharing with commercial 5G networks.

This article is based on an official press release from RTX.
On May 18, 2026, RTX’s Raytheon announced it was awarded a contract by the U.S. Office of Naval Research (ONR) to develop advanced software for next-generation naval radars. According to the official press release, this initiative aims to transition radar capabilities from traditional hardware-dependent systems to highly adaptable, software-defined architectures.
The core innovation of this contract centers on enabling individual building blocks within a single Radar-Systems to operate independently. This modular approach allows the radar to perform multiple missions simultaneously, a critical requirement for modern naval operations facing diverse and complex threats.
Furthermore, the technology focuses heavily on spectrum sharing. By relying on software updates rather than physical hardware redesigns, the U.S. Navy anticipates upgrading radar performance faster, at a lower cost, and with significantly reduced risk compared to legacy systems.
The Shift to Software-Defined Apertures
Raytheon’s Advanced Technology team is spearheading the project, which treats each radar building block as its own “software-defined aperture.” As detailed in the company’s announcement, this architecture ensures that operational modes, performance metrics, and mission functions can be modified entirely through software updates, bypassing the need for extensive hardware overhauls.
“The electromagnetic spectrum is more crowded than ever, and our systems have to be smarter about how they operate in it. With precise, software-driven control over where and how we radiate, we’re taking an important step forward in how we use software‑defined apertures to keep pace with evolving mission demands,” said Colin Whelan, President of Advanced Technology at Raytheon.
Navigating a Crowded Electromagnetic Spectrum
Coexisting with Commercial 5G
A primary driver for this technological leap is the increasingly congested radio frequency spectrum. As commercial wireless technologies, particularly 5G and upcoming 6G networks, expand globally, military radars face challenges in securing the wide, uninterrupted bands they traditionally require to detect threats.
The newly contracted software will allow naval radars to dynamically navigate and share these crowded frequencies. According to the provided project details, this capability ensures that military systems can operate effectively without losing operational effectiveness or interfering with civilian telecommunications networks.
Tactical Advantages and Future Deployment
Addressing Modern Maritime Threats
Modern naval vessels are confronted with complex, simultaneous threats, ranging from hypersonic missiles to swarms of aerial and surface drones. A radar system capable of independently tasking its internal modules to track diverse threat profiles simultaneously provides a distinct tactical advantage for the fleet.
The immediate roadmap for this technology involves software engineering by Raytheon, followed by a demonstration phase to validate independent module control and 5G spectrum-sharing capabilities. Upon successful validation, the technology is slated for direct transition into operational U.S. naval radar systems.
AirPro News analysis
We observe that the defense industry is undergoing a massive paradigm shift toward “open architecture” systems. Historically, upgrading a military radar necessitated taking a ship out of service to physically rip out and replace heavy hardware. By transitioning to software-defined systems, the U.S. Navy is effectively moving toward a model where warships can be upgraded much like smartphones, receiving new combat capabilities via software patches. This approach not only accelerates deployment timelines but also significantly reduces lifecycle costs and operational downtime, ensuring the fleet remains agile against rapidly evolving global threats.

India DAC Clears Rs 2.12 Lakh Crore Defence Acquisitions
India’s Defence Acquisition Council approved Rs 2,12,000 crore in military procurement, with 82% directed to domestic manufacturers.

India‘s Defence Acquisition Council cleared capital acquisition proposals valued at an estimated Rs 2,12,000 crore on October 26, 2026, directing the vast majority of the funds toward domestic aerospace and defence manufacturers.
The approvals, known as Acceptances of Necessity (AoN), mark the formal beginning of the procurement process for the Indian Armed Forces. According to a press release from the Press Information Bureau, approximately 82% of the cleared procurements will be sourced from Indian industry, underscoring the government’s ongoing push for military self-reliance.
Rotary-wing and weather surveillance modernization
The aviation and aerospace components of the clearance reflect modern battlefield priorities across multiple branches of the Indian military. A significant portion of the approval centers on modernizing the country’s rotary-wing fleets.
The Indian Air Force (IAF) and the Indian Army will jointly procure Light Multi Role Helicopters (LMRH). The government stated the LMRH will be utilized for “Reconnaissance and Surveillance, Combat, Search and Rescue of troops, Humanitarian Assistance and Disaster Relief.” The joint procurement strategy aims to standardize the utility helicopter fleet across the two branches.
In addition to the LMRH program, the IAF will acquire Special Utility Helicopters specifically configured for air transport operations. To support flight operations and tactical planning in forward areas, the IAF will also procure Mobile X-Band Doppler Weather Radar Systems. These mobile units are designed to provide high-resolution, localized weather surveillance, a critical capability for flight safety and mission execution in challenging environments.
Expanding unmanned and air defence capabilities
The October 26 clearance heavily emphasizes unmanned aerial systems and the corresponding technologies required to defeat them. The Indian Army’s drone capabilities will undergo a significant expansion through the acquisition of Long Range Kamikaze Drone Systems, Surveillance Unmanned Aerial Vehicles (UAV), and Integrated Surveillance and Strike Systems.
To counter emerging aerial threats, the armed forces will acquire Very Short-Range Air Defence Systems (VSHORADS). These systems provide terminal air defence against low-altitude aerial threats. The procurement also includes Platform Based Counter Unmanned Aerial Systems (C-UAS), which are specifically intended to protect armored formations from hostile drone activity.
The Indian Navy is also included in the aerospace and defence technology upgrades, with the council clearing the procurement of the Active Offboard Decoy System (AODS) to enhance maritime defensive capabilities.
The Acceptance of Necessity framework
The Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh, serves as the highest decision-making body within the Indian Ministry of Defence regarding military procurement. The council is responsible for clearing major capital acquisitions for the Indian Army, Navy, and Air Force.
In the Indian defence procurement system, an Acceptance of Necessity represents the in-principle administrative approval that initiates the formal acquisition process. It is the mandatory first step before the government can proceed with the acquisition.
Following the AoN clearance on October 26, 2026, the Ministry of Defence will issue Requests for Proposal (RFP) to domestic defence manufacturers. The issuance of RFPs will lead to a structured process of equipment trials, commercial negotiations, and eventual contract awards to the selected vendors.
AirPro News analysis
We view the allocation of 82% of a Rs 2,12,000 crore clearance to domestic industry as a definitive structural shift in the Indian defence market. The Ministry of Defence has been aggressively pushing its “Aatmanirbharta” (self-reliance) initiative to reduce dependence on foreign military imports and build a robust domestic manufacturing ecosystem. By ring-fencing such a massive capital outlay for local suppliers, the government is ensuring that the majority of the capital flows directly into the domestic aerospace and defence sectors.
For foreign original equipment manufacturers, this clearance reinforces the reality that direct, off-the-shelf sales to India are becoming increasingly rare. Accessing the Indian market now requires deep integration with domestic firms through joint ventures, technology transfers, and local manufacturing subsidiaries. The emphasis on domestic development for complex platforms like the Light Multi Role Helicopter also signals high government confidence in the maturity of local prime contractors and their supply chains.

RCAF Accepts First Two CF-35A Fighters at Luke Air Force Base
Canada takes delivery of CF-35A fighters AR-1 and AR-2 at Luke AFB as its C$19B procurement program remains under review.

This is original reporting and analysis by AirPro News.
The Royal Canadian Air Force (RCAF) officially accepted delivery of its first two Lockheed Martin CF-35A Lightning II stealth fighters at Luke Air Force Base in Arizona on October 22, 2026, marking the physical introduction of the fifth-generation platform into the Canadian military.
The handover of the aircraft, designated AR-1 and AR-2, proceeds even as the broader C$19 billion procurement program remains in political limbo. Following trade and diplomatic tensions with the United States, Prime Minister Mark Carney initiated a formal review of the 88-aircraft purchase in March 2025, leaving the ultimate size and composition of Canada’s future fighter fleet unconfirmed.
Initial training operations in Arizona
The first two CF-35As will remain stationed at Luke Air Force Base to support the initial training cadre of Canadian instructor pilots and maintainers. The Arizona installation serves as a primary international training hub for the F-35 platform, hosting multiple allied nations. According to the Department of National Defence (DND), a total of eight Canadian jets are planned to be based at the facility through 2026 and 2027.
The delivery occurred exactly one month after the first Canadian aircraft completed its maiden flight at Lockheed Martin’s production facility in Fort Worth, Texas, on September 23, 2026. In an official statement regarding the delivery, the RCAF noted that the arrival of the jets represents a foundational step, adding that the future of air and space power is built on more than equipment alone.
Procurement review and fleet uncertainty
Canada has been a partner in the Joint Strike Fighter program since 1997. After years of political debate and a reset of the procurement process, the Canadian government selected the F-35A in 2022 over the Saab Gripen E to replace its aging McDonnell Douglas CF-18 Hornet fleet. The CF-18 has been in service since the 1980s and is slated for retirement in the early 2030s. In January 2023, Ottawa finalized the agreement to purchase 88 F-35As.
The procurement trajectory shifted in March 2025 when Prime Minister Carney ordered a formal review of the acquisition. Currently, only 16 of the 88 jets are firmly committed and funded. Minister of National Defence David McGuinty confirmed the ongoing evaluation, stating that the question of the F-35 remains under review and that both he and the prime minister are highly engaged in the issue alongside the emerging Defence Investment Agency.
The government is actively evaluating the possibility of operating a mixed fighter fleet. This approach could integrate Saab Gripen E fighters alongside a smaller number of F-35s, reopening a competition that Saab had previously lost during the Future Fighter Capability Project selection.
Path to operational capability
Despite the political uncertainty surrounding the final fleet size, the RCAF continues to execute its transition plan for the funded aircraft. The first CF-35As are scheduled to arrive on Canadian soil at 4 Wing Cold Lake in Alberta in 2028.
The air force plans to declare Initial Operational Capability (IOC) for the CF-35A fleet between 2029 and 2030. This timeline aligns with the necessary infrastructure upgrades at Canadian bases and the completion of initial pilot and maintainer training in the United States.
AirPro News analysis
Canada’s ongoing review of the F-35 program is highly unusual for a Tier 3 partner at this late stage of procurement. While the physical delivery of AR-1 and AR-2 ensures the RCAF can begin building its fifth-generation institutional knowledge, the potential pivot to a mixed fleet introduces significant logistical and interoperability questions. Operating both the CF-35A and the Saab Gripen E would require maintaining two distinct supply chains, training pipelines, and maintenance infrastructures. We note that these dual-fleet requirements could potentially offset the initial acquisition savings of a split purchase, complicating the RCAF’s transition away from the CF-18 Hornet.

U.S. Army Validates AH-64E Apache Maritime Lifting Sling
The U.S. Army validated a lifting sling for the AH-64E Apache, enabling crane-based maritime loading with rotor blades folded.

The U.S. Army has successfully validated a prototype lifting sling for the Boeing AH-64E Apache, clearing the attack helicopter for crane-based maritime loading and unloading with its main rotor blades folded.
Announced on October 21, 2026, by the Apache Helicopter Project Office, the validation fulfills the final transportability requirement outlined in the aircraft’s Capability Production Document (CPD). The milestone significantly expands the Army’s expeditionary logistics options by reducing reliance on specialized port infrastructure.
Expanding maritime logistics capabilities
Prior to this validation, maritime deployment of the Apache fleet often depended on Roll-On/Roll-Off (RORO) vessels or specialized dock facilities equipped with ramps capable of supporting towed aircraft. The new sling, engineered by industry partner ASRC Federal, allows the AH-64E to be hoisted using standard harbor and shipboard cranes.
This Lift-On/Lift-Off (LOLO) capability mitigates transit bottlenecks and lowers vessel charter costs by opening access to a wider range of global seaports. The U.S. Army stated that the ability to load and unload the aircraft with its main rotor blades folded is a major milestone for expeditionary mobility.
Prototype validation and next steps
The validation exercise took place at Fort Hood, Texas, overseen by the Apache Project Management Transportability Team based at Redstone Arsenal, Alabama. During the testing, the team successfully demonstrated the safe hoisting of the AH-64E using the ASRC Federal prototype hardware.
Following the exercise, the test team identified minor adjustments required before full production. These modifications include the addition of protective padding to prevent the hoisting cable from contacting the main rotor blades during lifting operations. Once these adjustments are validated, ASRC Federal will manufacture and deliver five contracted production prototypes to the U.S. Army.
The AH-64E Apache global footprint
Manufactured by The Boeing Company, the AH-64 Apache has served as the primary attack helicopters for the U.S. Army since 1984. The AH-64E is the latest variant, featuring upgraded sensors, software, and weapons performance. The U.S. Army is currently modernizing its fleet to the AH-64E Version 6.5 standard while gradually retiring older AH-64D models.
The global Apache fleet consists of more than 1,280 aircraft operating across 19 defense forces. In March 2023, Boeing reported the U.S. Army fleet had surpassed 5 million total flight hours.
International demand for the platform remains active. On August 11, 2026, Boeing signed offset agreements with Polish industry partners to build a long-term sustainment infrastructure supporting Poland’s incoming fleet of 96 AH-64E helicopters.
AirPro News analysis
The shift from RORO dependency to LOLO capability represents a critical logistical upgrade for U.S. Army aviation. As military planners focus on distributed operations and expeditionary mobility, the ability to utilize commercial container ports and standard maritime cranes reduces reliance on specialized military sealift vessels. This transportability milestone ensures the AH-64E can be deployed more rapidly and flexibly in contested or infrastructure-limited theaters.
