It’s all about storm chasing when you want to find out the limits a helicopter can operate within, from a ship.
01 MAY, 2024
Last month, maritime sustainment ship HMNZS Aotearoa passed its First of Class Flight Trials in partnership with No. 6 Squadron for the operation of a Seasprite SH2-G(I) maritime helicopter from its flight deck.
The achievement means Aotearoa, the Royal New Zealand Navy’s newest ship since commissioning in 2020, is qualified to embark a Seasprite and use it for operations and exercises.
Every class of ship capable of embarking and operating a helicopter needs to conduct trials to ascertain Ship Helicopter Operating Limits (SHOLs) – the safe limitations for a specific helicopter type flying to and from that particular class of ship.
The trials experiment with wind direction, ship movement and weight parameters for launching and recovering that helicopter, by day and night.
The ship’s company and the flight crews have to learn how the wind behaves in relation to the superstructure of the ship and its course and speed, which could alter wind direction and strength over the flight deck. There’s also the ship’s roll and pitch to take into account, depending on how the ship is pointing into the relative swell.
Both the ship and Seasprite were fitted with precision instrumentation to correlate relative wind speed and direction with the helicopter’s performance. Readings of engine thrust, rotor torque, landing force and other parameters were taken into account.
The more variable and challenging the weather, the more complete the data gathered will be. Cruising around the Hauraki Gulf isn’t going to be enough.

“We were lucky with the weather,” says Aotearoa’s Ship Information Officer Ensign Emma Walker.
“We didn’t have to search too hard for rough seas and high winds.”
Training Flight Commander Lieutenant Commander Matt Snazell says the difficulty with the ship moving was working out where the waves were coming from.
“Aotearoa is such a big ship it’s quite difficult to tell. You see the swell break over the bow of the ship, but then it takes few seconds for it to get to the flight deck at the very end. You’re really just having to sit and wait for the opportune moment.”
“We did spend quite a lot of time going up and down with the ship and it looked quite hectic from the flight deck as it looked like we were moving all over the place,” he says.
The training enabled the helicopter crews to find the “edge of the night flying capability” – and they found it.
“We had a few issues with really strong winds and turbulance coming over, so we worked out there were certain areas we couldn’t use. We can’t have winds from a certain direction or at a certain strength.
“Strong winds from a really tricky direction means it’s not safe to oprate the helicopter, so that’s where we drew the line,” LTCDR Snazell says.
The crew used a combination of night vision goggles and flying unaided, using the lights from the ship.
Commander Rob Welford, Commanding Officer Aotearoa, says the trials took nine days.
“Finding the operating limits required the ship to seek out bad weather and this was achieved with the help of a meteorologist on board. A large swell was encountered near Cape Reinga, and strong winds off the East Cape.
“The biggest waves were eight metres high, our largest roll was nine degrees and largest pitch was 5.7 degrees.”
The trials required 28 hours of flying, 181 deck landings, plus 41 other trials such as transfer simulations and refuelling.
“It’s also a very good test of the ship’s organisation and ability to coordinate flying operations in all variations of weather and sea states,” Commander Welford said.
The launching ceremony of the first Hangor-class submarine constructed for the Pakistan Navy was held at Wuchang Shipbuilding Industry Group’s Shuangliu Base in Wuhan China.
The government of Pakistan signed a deal with CSOC of China for the acquisition of eight Hangor-class submarines.
Under the contract, four submarines will be built in China whereas the other four will be constructed in Pakistan at Karachi Shipyard & Engineering Works Ltd (KS&EW) under Transfer of Technology (ToT).
These Submarines will be fitted with modern weapons and sensors to engage targets at standoff ranges.
To remind, in February this year, the keel was laid for the second submarine in this class. The keel-laying ceremony was held at Karachi Shipyard & Engineering Works’ facilities.
Commissioned in 1938, she saw extensive service during World War II, taking part in fighting in the Mediterranean and Pacific theaters. Following the war the ship was decommissioned in 1946 and lay idle until sold to Argentina in 1951. Renamed ARA Nueve de Julio, the ship remained in service with the Argentinian Navy until 1978, after which she was taken to Brownsville, Texas and scrapped in 1983. https://en.wikipedia.org/wiki/USS_Boise_(CL-47)

In the Red Sea
U.S. ships continue to patrol the Red Sea as part of Operation Prosperity Guardian, the U.S.-led multinational effort to protect ships moving through the region. Houthi forces in Yemen continue to attack merchant shipping in the Red Sea and the Gulf of Aden, while U.S. naval forces in the region have continued strikes against Houthi weapons that U.S. Central Command says are a threat to naval and merchant ships. Houthi forces say they are targeting ships with connections to the United Kingdom, the U.S. and Israel.
The U.N. Security Council on Jan. 10 approved a resolution calling on Yemen’s Houthi rebel group to “cease its brazen” attacks in the Red Sea.
On Sunday, U.S. Central Command engaged five airborne unmanned aerial vehicles (UAVs) over the Red Sea.
On Friday, Iranian-backed Houthi terrorists launched three anti-ship ballistic missiles (ASBMs) from Houthi-controlled areas of Yemen into the Red Sea in the vicinity of MV MAISHA, an Antiqua/Barbados flagged, Liberia operated vessel and MV Andromeda Star, a UK owned and Panamanian flagged, Seychelles operated vessel. MV Andromeda Star reported minor damage but continued its voyage.
On Thursday, USCENTCOM engaged and destroyed one unmanned surface vessel (USV) and one UAV in Houthi-controlled areas of Yemen.
On Wednesday, USCENTCOM engaged and destroyed four UAVs over Houthi-controlled areas of Yemen.
In the Gulf of Aden
On Thursday, one ASBM was launched from Iranian-backed Houthi terrorist-controlled areas of Yemen into the Gulf of Aden.
On Wednesday, a coalition vessel successfully engaged one ASBM launched from Iranian-backed Houthi terrorist-controlled areas in Yemen over the Gulf of Aden. The ASBM was likely targeting the MV Yorktown, a U.S.-flagged, owned, and operated vessel with 18 U.S. and four Greek crew members, according to U.S. Central Command.
In the Persian Gulf
U.S. Coast Guard Sentinel-class Fast Response Cutters are forward-deployed to the region under Patrol Forces Southwest Asia (PATFORSWA). PATFORSWA deploys Coast Guard personnel and ships with U.S. and regional naval forces throughout the Middle East. Initially deployed in 2003 to support Operation Iraqi Freedom, PATFORSWA is now a permanent presence based out of the Kingdom of Bahrain.
In the Eastern Pacific
Amphibious assault shipUSS Boxer (LHD-4) returned to San Diego, Calif., delaying its deployment after suffering a casualty, USNI News reported. The two San Diego dry docks large enough to accommodate a big deck amphibious warship are currently occupied, complicating the repairs of Boxer.
Naval Sea Systems Command told USNI News last week that it has not yet made a decision on the way forward.
“Boxer is currently pier side at Naval Station San Diego. As inspections and assessments are continuing, a decision on the most efficient way to execute repairs is still being determined,” reads the statement.
In the Mediterranean and Eastern Atlantic
The ships carrying pieces to build a humanitarian aid pier in Gaza are now mostly in the Mediterranean Sea.
Three U.S. Army watercraft, a Military Sealift Command transport and a Maritime Administration ready reserve transport ship are off the coast of Gaza.
As of Monday, USAV General Frank S. Benson (LSV-1), USAV Montorrey (LCU-2030), USAV Matamoros (LCU-2026) were operating in the Eastern Mediterranean, along with Military Sealift Command ships USNS 1st Lt. Baldomero Lopez (T-AK-3010) and MARAD ship MV Roy P. Benavidez (TAKR-306). USAV SP4 James A. Loux (LSV-4) was in Souda Bay, according to ship spotters. USAV Wilson Wharf (LCU-2011) was in the Eastern Atlantic off the coast of North Africa, not yet in the Mediterranean Sea.
Lopez and USNS 2nd Lt. John P. Bobo (TAK-3008) were transporting parts of Naval Beach Group One’s similar floating pier system to operate in tandem with the Army’s system.
2nd Lt. John P. Bobo returned to Jacksonville, Fla., after experiencing a fire in its engine room, the Navy said Wednesday. The crew extinguished the fire and no injuries were reported. The fire is under investigation, according to the statement. As of Monday USNS GySgt. Fred. W. Stockham (T-AK-3008) was in Jacksonville.
The general concept will have the Army build a pier that it will anchor to the shore in Gaza, with no U.S. personnel setting foot on land. The Navy will build a transfer point two to three miles offshore where cargo – likely originating in Cyprus – will be transferred to the Army watercraft to be taken to the pier.
Based on the initial timelines, the pier could be completed by mid-May.
In the Western Atlantic
Aircraft carrier USS George Washington (CVN-73) departed Norfolk, Va. on Thursday en route its new homeport of Yokosuka, Japan.
As part of its transit, George Washington will participate in Southern Seas 2024, which seeks to enhance capability, improve interoperability, and strengthen maritime partnerships with countries throughout the U.S. Southern Command area of responsibility through joint, multinational and interagency exchanges and cooperation. The carrier is set to arrive at Naval Station Mayport, Fla., this week for an opening ceremony for the start of Southern Seas.
Amphibious assault ship USS Wasp (LHD-1) is operating off the East Coast.
Aircraft carrier USS Harry S. Truman (CVN-75) is underway conducting basic training.
In addition to these major formations, not shown are others serving in submarines, individual surface ships, aircraft squadrons, SEALs, Special Purpose Marine Air-Ground Task Forces, Seabees, EOD Mobile Units and more serving throughout the globe.
APRIL 29, 2024 5:58 PM – UPDATED: APRIL 29, 2024 11:51 PM
This post has been updated with a statement from U.S. forces in the Philippines.
U.S., Philippine, and French amphibs and frigates drew the attention of Chinese surveillance ships and surface combatants as they sailed out of Philippine territorial waters into the disputed waters of the South China Sea over the weekend during Manila’s largest annual military exercise.
The combined force, composed of USS Harpers Ferry (LSD-49), BRP Davao del Sur (LD 602), BRP Ramon Alcaraz (PS-16) and FS Vendémiaire (F 734), departed Puerto Princesa last Thursday to kick off the multilateral maritime exercise component of Balikatan 2024 with Chinese warships nearby.
Sailing to their planned exercise areas in the South China Sea, the ships were within Philippine archipelagic waters in the Sulu Sea during an uneventful first day at sea. However, after exiting territorial waters, at least two People’s Liberation Army Navy spy ships were spotted shadowing the multinational formation on Saturday.
One surveillance ship was identified as the Type 815-class electronic surveillance ship Tianwangxing (793). Philippine state media reported Tianwangxing was spotted near the exercise area, around 50 nautical miles from Western Palawan in the Philippine exclusive economic zone. Alongside the two spy ships, a Chinese frigate came within seven to nine nautical miles of the group on Sunday.
According to a TaiwanPlus reporter embarked on a Philippine Navy warship, the Chinese surveillance ship Tianwangxing sailed within two nautical miles of Harpers Ferry disrupting a live-fire drill with crew-served weapons. Following an earlier version of this post, two U.S. exercise spokespeople denied the Chinese ship disrupted the exercise to USNI News.
Armed Forces of the Philippines officials told local media that they were unbothered by the presence of PLAN ships because they received no provocations or disruptions to the exercise, stating that “as long [as] we continue to monitor and report them, we are in control of the situation, and besides the exercises are still ongoing.”
While maritime drills have occurred in previous iterations of Balikatan, this year’s exercise pushes the boundaries through its activities in the South China Sea. According to exercise plans, the drills will include “sailing within the bounds of the Philippines’ economic exclusive zone” and training for freedom of navigation operations.
France and the Philippines will also hold a separate bilateral exercise on Tuesday outside of the scope of Balikatan 2024. The patrol frigates Vendémiaire and Ramon Alcaraz will detach from the trilateral formation to conduct a bilateral sail in the South China Sea, although it’s unclear where or what drills the ships will perform. While the 2024 Balikatan is the first time Paris is participating, a French news release stated that Vendémiaire will leave the exercise before “it reaches its high-intensity phase,” referring to U.S.-Philippine coastal defense and amphibious assault drills.
Balikatan’s maritime component in the South China Sea wrapped up on Monday with a last-minute shadow of the PLAN Type 51B Luhai-class destroyer Shenzhen (167) and the inclusion of USS Somerset (LPD-25). The amphibs will now continue for other activities under Balikatan, such as amphibious assault and HIMARS rapid infiltration drills across Western Palawan. Somerset got underway over the weekend after stopping in Subic Bay for mid-voyage repairs. The amphibious transport dock has been operating in the Indo-Pacific since deploying in January. The ship is part of a split deployment of the Boxer Amphibious Ready Group and the 15th Marine Expeditionary Unit.
Before the beginning of Balikatan, the Philippine military stated that there were around 124 Chinese Maritime Militia vessels operating within the country’s EEZ, marking a drastic increase from the numbers usually operating in the area.
In 2022, the PLAN spy ship Haiwangxing (792) entered Philippine archipelagic waters and loitered around the Sulu Sea for three days claiming innocent passage. The Philippine government protested the incursion, stating that “[i]ts movements, however, did not follow a track that can be considered as continuous and expeditious, lingering in the Sulu Sea for three days.” These events also transpired during the U.S.-Philippine Marine Exercise 2022, which had several activities in Palawan.
Helping island nations, like Vanuatu, protect their resources and enforce their laws is “a sweet spot” for the Coast Guard’s operations in the Pacific, Commandant Adm. Linda Fagan said Monday.
Fagan used Vanuatu, a South Pacific nation spread over 80 islands, as an example to show how the Coast Guard can partner with other nations. Vanuatu’s ship riders were on USCGC Harriet Lane (WMEC-903) and boarded several Chinese vessels suspected of illegal fishing in its exclusive economic zone, she said.
“During the operation, Vanuatu officers supported by U.S. Coast Guard crew members … found multiple violations of Vanuatu law. The operation was made possible by a 2016 ship rider agreement between the United States and Vanuatu, which enables Vanuatu maritime law enforcement officers to ride aboard U.S. Coast Guard cutters and enforce Vanuatu’s laws within its waters,” the American embassy in the capital Port Vila said in a release
Fagan said Harriet Lane was now homeported in Honolulu to “create more [Coast Guard] presence” in the Indo-Pacific. She added the service expects to add two fast response cutters to its operations there.
The Coast Guard requested $263 million to increase presence and missions in the Indo-Pacific for Fiscal Year 2025.
“Illegal fishing is absolutely a global problem” that can dramatically impact small nations’ abilities to feed their citizens, the Coast Guard commandant said.
“[The] Coast Guard is operating as a professional military force” that “is[operating] consistent with international law,” Fagan said. She pointed to transit of cutters through the 90-mile wide Taiwan Strait as an example of that and the Coast Guard’s close alignment with the Pentagon’s Indo-Pacific Command in missions and operations.
She noted that other nations, including the United Kingdom’s Royal Navy, have capacity-building missions similar to the Coast Guard’s Mobile Training Teams.
The “long, long relationship” with Japan serves as an example of the service’s presence in the Pacific that now extends to missions with India. The service will again participate in this year’s Rim of the Pacific [RIMPAC] exercise, which is expected to have 29 nations participating.
On the Coast Guard’s largest capital shipbuilding program, the Polar Security Cutter, Fagan said, “we’re on budget [and] we’re really going to lean into it. It’s important to be cutting steel for this.”
The cutter is being built at Bollinger Shipyard in Pascagoula, Miss. It is the first heavy icebreaker to be built in the United States in 50 years. She added USCGC Polar Star (WAGB-10), the nation’s only heavy icebreaker, will be completing maintenance work at Mare Island, Calif., and be available for Antarctic service this fall. Fagan added Polar Star was her first cutter after commissioning into the service.
On delays in delivery and repair work, “we’re competing with the Navy” for space in shipyards for both building and repair, she said. “We’re all operating with scarce capacity,” she said. Fagan praised the efforts the Navy has put into modernizing American shipyards to improve efficiency, expand operations and attract and retain a skilled workforce.
At the same time, the Navy and Coast Guard are also competing with the shipyards in attracting and retaining workers who can be trained or already are “welders, pipefitters, electricians. You don’t grow that overnight.”
The Coast Guard stepped up recruiting efforts, Fagan said.
“Maybe, I’m biased, I think … we’re the world’s best military [service]. You won’t find a better organization in the world,” Fagan said.
Like all the uniformed services, recruiting has proved a growing challenge as the economy rebounded from the impact of the COVID-19 pandemic on job opportunities.
In early April, the Coast Guard announced a comprehensive talent management initiative, examining billets against the military’s traditional up-or-out pyramid. It also is simplifying recruiting procedures and adjusting initial training to take into account recruits’ skills when enlisting. The service was down 2,500 recruits from mission.
“We’re moving away from a rigid one-size-fits-all system to one that enables every individual to perform to their full potential,” she said at the annual Coast Guard dinner in March. “It’s a generational change in our approach to talent management.”
Cardigan Bay sailed from Cyprus to help support the international effort to build the pier, which will reportedly cost $320m and is set to be completed early next month.
In photos released by US Central Command, special construction vessels can be seen assembling the pontoon and a large vehicle is pictured moving and assembling shipment containers.
The 550-metre causeway will enable more aid to be brought into Gaza, including as many as two million meals a day.
So far, aid has had to be parachuted into Gaza, with a number of air drops being undertaken by an international coalition.
