PHOENIX — Honeywell has successfully demonstrated several advanced alternative navigation technologies intended to help ensure seamless navigation, even when GPS signals are blocked, interrupted or unavailable, Ahjay Rai of Honneywell said in an April 20 release.

Testing took place on both an Embraer E170 aircraft and an AgustaWestland AW139 helicopter. 

Alternative navigation systems use sensors such as cameras, star trackers, radars and radios to augment and or aid inertial navigation systems. These systems correct inertial navigation systems in environments where global navigation satellite systems are denied. 

“Our customers are seeing an increase in both intentional and unintentional navigational disruptions, including jamming for GNSS-based navigation,” said Matt Picchetti, vice president and general manager of Navigation and Sensors at Honeywell Aerospace. “There hasn’t been a single set of solutions that meet all our customers’ operational needs, so we decided to create one. Our modular and scalable alternative navigation technologies are setting a new benchmark in terms of reliability and performance in GNSS-denied environments compared with what is available in aviation today.” 

Alternative navigation technologies provide position, velocity and heading information in GNSS-denied environments. The successfully demonstrated technologies onboard the E170 and AW139 include: 

• Vision Aided Navigation: Honeywell’s Vision Aided Navigation system achieved GPS-like performance on both the Embraer E170 and AW139 platforms during GPS-denied conditions. Additionally, the technology showed 67% improvement in GPS-denied performance compared with earlier testing last year. The system uses a live camera feed and compares it with maps to provide a passive, not jammable, and highly accurate absolute position. 
• Celestial Aided Navigation: Honeywell’s Celestial Aided Navigation system on the Embraer E170 achieved an accuracy of 25 meters circular error probability of 50% (CEP50). This represented a 38% improvement in GPS-denied performance compared with tests last year. Most importantly, this is the first time a Resident Space Objects-based (RSOs) navigation solution was demonstrated on an airborne platform, as most competing solutions rely only on star-based navigation. The system utilizes a star tracker to observe stars and RSOs to provide a passive, not jammable solution with GPS-like accuracy in GPS-denied or spoofed conditions. 
• Magnetic Anomaly Aided Navigation: Honeywell conducted the world’s first real-time magnetic anomaly-aided navigation on an airborne platform, the Embraer E170. This is a historic milestone, as almost all previous magnetic tests were done in special environments to mitigate electromagnetic noise. Honeywell demonstrated this passive, not jammable, all-weather, 24/7 technology on an embedded platform, which measures earth’s magnetic strength and compares it with magnetic maps to accurately identify the position of the vehicle. 

Additionally, Honeywell demonstrated inertial navigation systems, when paired with the GPSDome (anti-jamming device), showed significant improvement in position accuracy and integrity performance in the presence of GPS jamming. The ability of GPSDome to enable tracking of GPS satellites under more aggressive jamming environments reduces performance degradations that come with GNSS-denied conditions. 

Alternative navigation prototype systems will be available in 2022, with initial deliveries expected to start in 2023. 

ARLINGTON, Va. — The Marine Corps’ new CH-53K King Stallion heavy-lift helicopter achieved initial operational capability on April 22, Deputy Commandant for Aviation Lt. Gen. Mark Wise said in an April 25 release.

The first fleet CH-53K squadron, HMH-461, now has at least four CH-53Ks, the minimum number needed to reach IOC and the number needed for a detachment to deploy with a Marine Expeditionary Unit.

“In addition to meeting IOC criteria, the CH-53K successfully completed a thorough initial operational test and evaluation period that resulted in over 3,000 mishap free hours flown in various challenging environments and terrain,” the release said.

“My full confidence in the CH-53K’s ability to execute the heavy lift mission is the result of successful developmental and operational testing conducted by Air Test and Evaluation Squadron (HX) 21 and Marine Operational Test and Evaluation Squadron (VMX) 1,” Wise said in the release.

The first deployment of the CH-53K is set for 2024. The Corps plans to field 5.25 fleet HMH squadrons with CH-53Ks. Col. Jack Perrin, the CH-53K program manager, told reporters earlier this month the “.25” is an extra four aircraft for one of the squadrons, with each of the other four squadrons to be equipped with 16 helicopters. Other CH-53Ks will be assigned to a fleet replacement squadron and test squadrons, while others will be in process through the maintenance pipeline.

The Marine Corps’ seven HMH squadrons equipped with the older CH-53E in recent years have operated with only 12 helicopters instead of 16 because of attrition over the years. One CH-53E squadron was deactivated last week and two more will be deactivated in the course of the commandant’s Force Design 2030 plan.

“The success to date of the CH-53K is a reflection of the hard work and effort by the Marines, Sailors and civilians at VMX-1, H-53 Program Office [PMA-261] and Marine Heavy Helicopter Squadron [HMH] 461, and the support we have received over many years from across the Department of the Navy and our industry partners,” Wise said.

The CH-53K is capable of providing nearly three times the lift capability of the CH-53E.

“The most notable attribute of the King Stallion is its ability to maintain increased performance margins in a degraded aeronautical environment, for example at higher altitudes, hotter climates and carrying up to 27,000 [pounds] out to 110 nautical miles; whereas, the CH-53E would be limited to a 9,628-pound external load in the same environment,” the release said.

“The King Stallion boasts an engine that produces 57% more horsepower with 63% fewer parts relative to its predecessor, which translates to an expanded capability to deliver internal and external cargo loads, providing the commander a mobility and sustainment capability the MAGTF [Marine Air-Ground Task Force] has never had before.”

Supporting the Corps’ Force Design 2030, “the CH-53K will complement connectors that will enable littoral maneuver and provide logistical support to a widely disaggregated naval force.”

The Marine Corps has a requirement for 200 CH-53Ks. Full-rate production is planned for 2023. Full operational capability is scheduled for 2029.

ARLINGTON, Va. — The U.S. Navy has proposed in its 2023 budget to decommission the amphibious command ship USS Mount Whitney (LCC 20) during fiscal 2026. 

The Mount Whitney has served as the flagship of the U.S. 6th Fleet since 2005, when it replaced the USS LaSalle (AGF 3).  

The Navy is proposing the retirement of the Mount Whitney because its retirement “is mitigated by staff operating ashore,” the service said in its 2023 budget highlights book, citing a savings of $179.7 million over the Future Years Defense Plan. 

The 6th Fleet staff normally is stationed ashore in Naples, Italy. The Mount Whitney is homeported in nearby Gaeta.  

The Mount Whitney is a Blue Ridge-class amphibious command ship. It was commissioned on Jan. 16, 1971, and served until 2005 as the flagship of the U.S. 2nd Fleet. It underwent conversion to a Military Sealift Command ship and is operated by a hybrid Navy/Civilian Mariner crew but remains a commissioned ship under the command of a Navy captain. If retired in 2026, the ship will have served 55 years.  

Currently, the Mount Whitney is deployed to the Red Sea and Gulf of Aden where it serves as the flagship of commander, Task Force 153, a new task force of the Combined Maritime Forces, an international coalition operating under commander, U.S. 5th Fleet/Naval Forces Central Command. 

GOLETA, Calif. and ORLANDO, Fla. ― Teledyne FLIR announced the release of its high-performance Hadron 640R combined radiometric thermal and visible dual camera module on April 25.

This includes offering drivers for market-leading processors from NVIDIA, Qualcomm, and more, plus industry-leading integration support and service from a support team of experts. It also offers flexible 60 Hz video output via USB or MIPI compatibility. Hadron 640R is a dual use product and is classified under U.S. Department of Commerce jurisdiction.

RAMSTEIN, Germany — The U.S. Marine Corps has deployed one of its units along with an AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) to Lithuania for the first time to support NATO’s enduring air policing mission, NATO’s Allied Air Command Public Affairs Office said April 25. 

This unit provides multi-domain command and control, air defense, air traffic control, radar surveillance and communications support. The G/ATOR allows Marines to conduct air surveillance and air domain awareness in support of NATO operations. 

“This deployment highlights the expeditionary character of our Marines and the command-and-control systems they employ such as the AN/TPS-80 G/ATOR,” said Col. Michael McCarthy, commanding officer of the deployed unit. “With little notice and a light footprint we were able to seamlessly move from training in an arctic, maritime environment to the Baltics; reassuring allies and immediately contributing to USAFE [U.S. Air Forces Europe] and NATO operations.” 

The Marine Corps unit deployed in support of Norwegian led Exercise Cold Response 22 before repositioning to Lithuania. They are a command-and-control unit, which provides multi-domain command and control, air defense, air traffic control, radar surveillance, and communications support. The AN/TPS-80 G/ATOR is the Marine Corps’ newest medium range multi-role radar. The radar builds an airspace picture for controllers through active scanning. 

DAHLGREN, Va. — Engineers at NSWC Dahlgren Division have developed a new, lower-in-cost, semi-active laser (SAL) seeker, the division said April 25.  

SAL seekers are a key enabling technology for guided munitions that allow warfighters to target stationary and moving targets in areas where GPS is unavailable. SAL seekers function in tandem with an operator that directs a pulsing, infrared laser at targets. The seeker, typically in the nose of laser-guided munitions, detects the laser energy reflecting off the target and guides the munition to the operator’s mark with high precision. This partnership assures that the correct target is engaged.  

The seeker developed by engineers at Dahlgren Division is smaller, three to five times cheaper than comparable laser seekers and is based on modern electronics designs not only to ensure relevance, but also to improve performance and implement the next generation of signal processing and countermeasures. As precision weapons requirements continue to expand, the design is ready to support integration with imager systems. The upgraded terminal seekers will be instrumental in the development of future guided munition systems.  

“In response to the shift in force design, warfighting function and the trends going forward, we’re technologically pivoting to stay ahead of the game,” said program manager for the Enhanced Expeditionary Engagement Capability program Luke Steelman.  

Traditional SAL seeker systems use a gimbaled detector element to track the laser spot as it moves relative to the weapon. Engineers at Dahlgren were able to develop a new combination of fixed optics and software algorithms to replicate the capability without the need for those expensive and sensitive moving parts. This has not only led to a smaller and more cost-effective product, but also one that is instrumental in ensuring compatibility with the next generation of system currently under development.  

What’s more, the new seeker design also includes an integrated height-of-burst sensor that is able to measure proximity to the ground and signal the weapon’s fuze to create a very precise airburst function without the need of an additional sensor on the guided munition, further saving space and reducing cost.  

Dahlgren has produced more than 50 prototypes, 30 of which have been live-fire tested on multiple weapon systems — including the 81-mm Advanced Capability Extended Range Mortar — and successfully guided systems to stationary and moving targets.  

Michael St. Vincent, project lead engineer, said that direct feedback from warfighters was critical to the successful development process.  

“We would get feedback from warfighters — what kind of targets they are targeting, what they are like, and also what requirements they need to meet,” said St. Vincent. “If they needed more range or more field of view . . . we would do simulations and make some changes and new iterations that moved closer to what they want.”  

Dahlgren has long had a hand in terminal seeker technology, but in recent years the focus of the warfighting function has moved to exceedingly longer-range engagements. These long-range engagements keep warfighters and targeting assets far away from adversaries, but often preclude the use of laser-guided munitions.  

Despite increasing engagement distances, Steelman says that laser-guided munitions that use the SAL seeker will always be a mainstay in warfighters’ toolboxes for one reason: target assurance.  

“If the operator is putting a dot on a target, he is telling me ‘this is your target, not the one to the left, not the one to the right, that one,’” St. Vincent noted. “Laser guidance will always provide that 99.99-percent assurance that a specific truck or boat is your target.” 

JACKSONVILLE, Fla. — The Arleigh Burke-class guided-missile destroyer USS Donald Cook (DDG 75) returned to Naval Station Mayport following a three-month deployment, April 24, the U.S. 2^nd Fleet said in an April 25 release. 

Donald Cook departed Naval Station Mayport in January on a short-notice deployment to operate with NATO Allies and partners in the Eastern Atlantic, North Sea and Baltic Sea. 
 
The crew spent more than 70 days at sea and conducted three port visits in support of maritime security partnerships in Copenhagen, Denmark; Rostock, Germany; and the Isle of Portland, England. 
 
“Visiting other counties as a representative of the United States is surreal,” said Fire Controlman (Aegis) 2nd Class Brady Itkin. “People told us how nice Americans are everywhere we went, and we were shown amazing hospitality by the civilians of other NATO countries. There’s no better feeling than making a positive impact on other people’s perspective of America.” 
 
The ship received warfare excellence awards in communications, engineering and ship safety while underway. 
 
“The crew put in a lot of hard work over the past year,” said Ensign Benjamin Steen, electronic warfare officer aboard Donald Cook. “This recognition is definitely a testament to all of our efforts.” 
 
While deployed, Donald Cook participated in NATO Exercise Dynamic Guard 2022 in the North Sea. Dynamic Guard, hosted by Norway, is a biannual, multinational electronic warfare exercise series designed to provide tactical training for the NATO Response Force and NATO national units. For the first time in three years, two U.S. vessels participated to further enhance the ongoing cooperation, strength and interoperability between NATO Allies. 
 
“The crew demonstrated their tenacity by executing multinational exercises and national tasking on short notice during this surge deployment,” said Cmdr. Matt Curnen, commanding officer of Donald Cook. “Our operations over the past few months have demonstrated our proficiency and capability as well as reaffirming our commitment to the NATO Alliance. I could not be more proud of the resiliency and professionalism the crew displayed during this deployment.” 
 
Donald Cook is scheduled to start a major maintenance availability, its first since returning from their former homeport of Rota, Spain, in June. 

PHILADELPHIA — Philly Shipyard Inc. will build one additional National Security Multi-Mission Vessel, or NSMV, the fifth and final in the training ship series.

The vessel, built under an order from TOTE Services as authorized by the Maritime Administration, will replace the aging training vessel at California State University Maritime Academy in Vallejo, California.

Construction of the new vessel, NSMV 5, is expected to commence in 2023. The contractual delivery date for NSMV 5 is 2026.

The order was placed under the April 2020 contract with TOTE Services, which allows for the construction of up to five NSMVs. The initial award included the first two vessels in the NSMV program, NSMVs 1 and 2. The next two vessels in the NSMV program, NSMVs 3 and 4, were ordered in January 2021.

The award for NSMV 5 is valued at approximately $300 million, bringing the total order intake under the contract for the five-ship program to be approximately $1.5 billion.

As announced in November 2021, Philly Shipyard’s order backlog also includes a contract from Great Lakes Dredge & Dock Co. to construct one Jones Act-compliant Subsea Rock Installation Vessel, with a contract value of approximately $200 million. The SRIV will be constructed in between NSMVs 4 and 5.

“It is truly a great day for Philly Shipyard as we are now responsible for building the complete series of the NSMV program — a physical symbol of MARAD’s investment in the future of maritime education and training,” said Steinar Nerbovik, president and CEO of Philly Shipyard. “The NSMV program continues to mark a turning point in our company’s transformation to serve both commercial and government markets.”

WASHINGTON — The Navy’s newest berthing barge, Auxiliary Personnel Lighter (APL) 69, recently conducted builder’s and acceptance trials in Pascagoula, Mississippi, Team Ships Public Affairs said in a release. 

Builder’s trials consist of a series of in-port tests and demonstrations that allow the shipbuilder, VT Halter Marine, and the Navy to assess the craft’s systems to ensure installation in accordance with the original equipment manufacturer’s guidelines and that the craft design and configuration meet the contract requirements.  

Acceptance trials consist of integrated testing to demonstrate the capability of the platform and installed systems across all mission areas to effectively meet its requirements. These tests and demonstrations are witnessed by the Navy’s Board of Inspection and Survey and are used to validate the quality of construction and compliance with specifications prior to delivery to the Navy.  

“These vessels improve quality of life for our Sailors during ship maintenance availabilities and inter-deployment training cycles,” said Capt. Eric Felder, program manager for U.S. Navy and Foreign Military Sales Boats and Craft, Program Executive Office Ships. “We look forward to delivering more of these vessels to the fleet to provide the necessary berthing, messing, administrative, and leisure facilities to crews while their ships are undergoing maintenance.” 

APLs are 82-meter-long barges that can berth up to 609 people — 72 officers and 537 enlisted personnel. Mess seating is available for 224 enlisted personnel, 28 chief petty officers and 28 officers in 20-minute intervals, allowing food service for 1,176 personnel with three meals a day.  

APLs are used to house duty crews while ships are in maintenance availabilities and can be towed to new bases or shipyards to support changing fleet requirements. Additionally, they offer the potential use for humanitarian missions and other temporary assignments. APLs are equipped with offices, classrooms, washrooms, laundry facilities, a medical treatment facility, a barber shop and a fitness center. 

VT Halter Marine is currently in production of two additional APLs. 

ARLINGTON, Va. — The Marine Corps plans to lease two commercial ships over the next two years to experiment with the light amphibious warfare ship concept, also now being classed as the landing ship-medium. 

Brig. Gen. Mark Clingan, assistant deputy commandant for Combat Development and Integration and deputy commanding general of Marine Corps Combat Development Command, speaking April 21 in a webinar of the National Defense Industrial Association, said the Corps was planning to lease a commercial “stern[-ramp] landing vessel” by late summer or early fall [2022]” to use to test the LAW/LSM concept. 

Clingan said a second vessel would be leased in fiscal 2023 for the same purpose. 

The general said the Corps also was looking at using Spearhead-class expeditionary fast ships — which do not have beach landing ramps — and utility landing craft — which do — as part of the concept experimentation. 

The LAW will be designed to carry 75 Marines of a Marine Littoral Regiment and land them on a shore in support of distributed maritime operations and expeditionary base operations. Clingan said the ships would be able to operate within the weapons engagement zone and be less attractive targets for enemy missiles than would a larger amphibious warfare ship.  

Clingan said that with each Marine Littoral Regiment comprised of nine platoons or units of action — one on each light amphibious warfare ship — 27 LAWs would be needed to support the three MLRs. Counting extra MLRs in the maintenance pipeline, the Corps lists 35 LAWs as its probable requirement.  

The Navy plans to procure the light amphibious warfare ship beginning in fiscal 2025.
