The Apache attack helicopter is a combat proven aircraft manufactured by American aerospace and defence company Boeing for the US Armed Forces.
AH-64 in Afghanistan
The AH-64 Apache will remain the US Army’s primary armed helicopter for several more decades, thanks to the collapse of the RAH-66 Comanche program, and the retirement sans replacement of the US Army’s Armed Reconnaissance Helicopter (ARH). Apaches also serve with a number of American allies, some of whom have already expressed interest in upgrading or expanding their fleets.
The AH-64E Guardian Block III (AB3) is the helicopter’s next big step forward. It incorporates 26 key new-technology insertions that cover flight performance, maintenance costs, sensors & electronics, and even the ability to control UAVs as part of manned-unmanned teaming (MUT). In July 2006, Boeing and U.S. Army officials signed the initial development contract for Block III upgrades to the current and future Apache fleet, via a virtual signing ceremony. By November 2011, the 1st production helicopter had been delivered. So… how many helicopters will be modified under the AH-64 Block III program, what do these modifications include, how is the program structured, and what has been happening since that 2006 award? The short answer is: a lot, including export interest and sales.
Some nations have aircraft carriers. The USA has super-carriers. The French Charles De Gaulle Class nuclear carriers displace about 43,000t. India’s new Vikramaditya/ Admiral Gorshkov Class will have a similar displacement. The future British CVF Queen Elizabeth Class and related French PA2 Project are expected to displace about 65,000t, while the British Invincible Class carriers that participated in the Falklands War weigh in at just 22,000t. Invincible actually compares well to Italy’s excellent new Cavour Class (27,000t), and Spain’s Principe de Asturias Class (17,000t). The USA’s Nimitz Class and CVN-21 Gerald R. Ford Class, in contrast, fall in the 90,000+ tonne range. Hence their unofficial designation: “super-carriers”. Just one of these ships packs a more potent air force than many nations.
Nimitz Class cutaway
As the successor to the 102,000 ton Nimitz Class super-carriers, the CVN-21 program aimed to increase aircraft sortie generation rates by 20%, increase survivability to better handle future threats, require fewer sailors, and have depot maintenance requirements that could support an increase of up to 25% in operational availability. The combination of a new design nuclear propulsion plant and an improved electric plant are expected to provide 2-3 times the electrical generation capacity of previous carriers, which in turn enables systems like an Electromagnetic Aircraft Launching System (EMALS, replacing steam-driven catapults), Advanced Arresting Gear, and integrated combat electronics that will leverage advances in open systems architecture. Other CVN-21 features include an enhanced flight deck, improved weapons handling and aircraft servicing efficiency, and a flexible island arrangement allowing for future technology insertion. This graphic points out many of the key improvements.
DID’s CVN-21 FOCUS Article offers a detailed look at a number of the program’s key innovations, as well as a list of relevant contract awards and events.

The British Ministry of Defense is reportedly investigating the supply of Royal Air Force (RAF) Eurofighter Typhoon Tranche 1 fighter jets to European MiG-29 operators. The ultimate aim is to replace the Soviet-era MiG 29 planes gifted by these operators to Ukraine, with these advanced Eurofighter aircraft. In parallel, Poland is considering gifting its Soviet-made MiG-29 fighters to Ukraine within the next four to six weeks, a move that would bolster Ukrainian forces’ firepower. These planes are already familiar to the country’s air force and can be utilized immediately. However, both the UK and Poland have stated that this supply would be part of a larger international coalition. Other countries, including Slovakia, have also declared their readiness to provide their MiG-29 planes to Ukraine, and NATO nations have urged others to come forward.
The Swedish Defense Materiel Administration (FMV) has demonstrated a new battle management system (BMS) for the Swedish Armed Forces. Called the BMS 3.1.2, the capability grew out of trials to develop a command support system for the combat vehicles of the Swedish Army’s two training companies. An initial system, dubbed the LSS Mark 2.0, was fielded in 2021 but had technical deficiencies, according to FMV.

Russia said Wednesday it had started naval exercises with China and Iran in the Arabian Sea as it seeks to shore up ties with Beijing and Tehran. The Russian defense ministry said in a statement that the trilateral exercises dubbed the “Marine Security Belt 2023” had begun in the vicinity of the Iranian port of Chabahar. The naval part of the drills will take place on Thursday and Friday.
LPD-17 San Antonio class amphibious assault support vessels are just entering service with the US Navy, and 11 ships of this class are eventually slated to replace up to 41 previous ships. Much like their smaller predecessors, their mission is to embark, transport, land, and support elements of a US Marine Corps Landing Force. The difference is found in these ships’ size, their cost, and the capabilities and technologies used to perform those missions. Among other additions, this new ship is designed to operate the Marines’ new MV-22 Osprey tilt-rotor aircraft, alongside the standard well decks for hovercraft and amphibious armored personnel carriers.
While its design incorporates notable advances, the number of serious issues encountered in this ship class have been much higher than usual, and more extensive. The New Orleans shipyard to which most of this contract was assigned appears to be part of the problem. Initial ships have been criticized, often, for sub-standard workmanship, and it took 2 1/2 years after the initial ship of class was delivered before any of them could be sent on an operational cruise. Whereupon the USS San Antonio promptly found itself laid up Bahrain, due to oil leaks. It hasn’t been the only ship of its class hurt by serious mechanical issues. Meanwhile, costs are almost twice the originally promised amounts, reaching over $1.6 billion per ship – 2 to 3 times as much as many foreign LPDs like the Rotterdam Class, and more than 10 times as much as Singapore’s 6,600 ton Endurance Class LPD. This article covers the LPD-17 San Antonio Class program, including its technologies, its problems, and ongoing contracts and events.

Italian Eurofighters
The multi-national Eurofighter Typhoon has been described as the aerodynamic apotheosis of lessons learned from the twin engine “teen series” fighters that began with the F-14 and F-15, continued with the emergence of the F/A-18 Hornet, and extended through to the most recent F/A-18 Super Hornet variants. Aerodynamically, it’s a half generation ahead of all of these examples, and planned evolutions will place the Eurofighter near or beyond parity in electronic systems and weapons.
The 1998 production agreement among its 4 member countries involved 620 aircraft, built with progressively improved capabilities over 3 contract “tranches”. By the end of Tranche 2, however, welfare state programs and debt burdens had made it difficult to afford the 236 fighters remaining in the 4-nation Eurofighter agreement. A 2009 compromise was found in the EUR 9 billion “Tranche 3A” buy, and the program has renewed its efforts to secure serious export sales. Their success will affect the platform’s production line in the near term, and its modernization plans beyond that.
Northrop Grumman won a $57.5 million modification, which exercises options to provide continued sustainment, engineering, logistics, and test support for MQ-4C Triton air vehicles, mission control and operator training systems; continued field service representative’s technical support to ensure that the MQ-4C Triton Unmanned Aerial System (UAS) aircraft are mission-capable for intelligence, surveillance and reconnaissance missions supporting aircraft early operational capability and initial operating capability; and continued reach-back engineering support for both the Navy and the government of Australia MQ-4C Triton UAS assets. Work will be performed in Patuxent River, Maryland (36.5%); San Diego, California, California; Jacksonville, Florida; Mayport, Florida; Baltimore, Maryland; various location within the continental US (CONUS); and various location outside CONUS (12.7%), and is expected to be completed in March 2024.
Russia’s relations with the United States are in a “lamentable state” and at their lowest level after a Russian jet downed one of the US’ drones, the Kremlin has said. The US said a Russian fighter plane caused its drone MQ-9 Reaper to crash into the Black Sea on Tuesday, marking the first direct encounter between US and Russian forces since Moscow invaded Ukraine.

Madrid’s unresolved orders for the Airbus A400M airlifter, the biggest defense project in Europe, are in turmoil and may have a significant impact on aviation investment in one of Airbus’s co-founding nations. Sources in the defense sector have disclosed that Spain is becoming increasingly hesitant about delivering the remaining 13 planes from their initial order of 27, indicating that the Spanish Air Force may not require them. This implies that only 14 A400M cargo planes will be in service with the Spanish Air Force. Designed to boost the strategic autonomy of seven European NATO nations, the A400M project has been hit by cost overruns and delays. As a result, any decision over the future of the A400M is expected to trigger intense negotiations over alternative defense orders and Airbus’s ongoing investment in Spain.
