China's Aircraft Carrier Ambitions
CHINA’S AIRCRAFT CARRIER AMBITIONS An Update Nan Li and Christopher Weuve his article will address two major analytical questions. First, what are the T necessary and suffi cient conditions for China to acquire aircraft carriers? Second, what are the major implications if China does acquire aircraft carriers? Existing analyses on China’s aircraft carrier ambitions are quite insightful but also somewhat inadequate and must therefore be updated. Some, for instance, argue that with the advent of the Taiwan issue as China’s top threat priority by late 1996 and the retirement of Liu Huaqing as vice chair of China’s Central Military Commission (CMC) in 1997, aircraft carriers are no longer considered vital.1 In that view, China does not require aircraft carriers to capture sea and air superiority in a war over Taiwan, and China’s most powerful carrier proponent (Liu) can no longer infl uence relevant decision making. Other scholars suggest that China may well acquire small-deck aviation platforms, such as helicopter carriers, to fulfi ll secondary security missions. These missions include naval di- plomacy, humanitarian assistance, disaster relief, and antisubmarine warfare.2 The present authors conclude, however, that China’s aircraft carrier ambitions may be larger than the current literature has predicted. Moreover, the major implications of China’s acquiring aircraft carriers may need to be explored more carefully in order to inform appropriate reactions on the part of the United States and other Asia-Pacifi c naval powers. This article updates major changes in the four major conditions that are necessary and would be largely suffi cient for China to acquire aircraft carriers: leadership endorsement, fi nancial affordability, a relatively concise naval strat- egy that defi nes the missions of carrier operations, and availability of requisite 14 NAVAL WAR COLLEGE REVIEW technologies. -

The unique characteris- tic of this ship is its aircraft-carrier-like design, with a “through” flight deck and an island on the starboard side. Hyuga was planned in the five-year Midterm De- fense Buildup Plan (MTDBP) of 2001 and funded in Japanese fiscal year (JFY) 2004 as the replacement for the aging first-generation helicopter-carrying de- stroyer (DDH), JS Haruna (DDH 141), which was to reach the end of its service life of thirty-five years in 2009. The second ship of the new class, JS Ise (DDH 182), of the JFY 2006 program, was commissioned 16 March 2011. -

SKI-JUMP LIMITATIONS and PLAN's SOLUTIONS
CAPS In Focus 25 July 2017 www.capsindia.org 61/17 SKI-JUMP LIMITATIONS AND PLAN’s SOLUTIONS Arjun Subramanian P Reports on Chinese naval aviation have been in the news lately and Chinese media is abuzz with photographs of the J-15 fighters operating from the PLAN’s first carrier – the Liaoning. The carrier was en-route to Hong Kong1 along with two escort warships when the flight operations were conducted. The PLAN even released a long video of the operations which gives some insights into the J-15 fighter and the role it will play. There is also some news on China building a carrier borne AEW aircraft to be operated from its CV-001 type vessels.2 China’s lone carrier, the refurbished old Soviet vessel – Varyag – is PLAN’s first experience with an aircraft carrier which it is so actively and boastfully projecting. China is steadily improving and adding up to its naval power projection capability. The released video was of very good resolution where every minute detail was visible and which enables inference of certain information.3 The video primarily contains take-offs and landings of the J- 15 fighter with and without load-outs. In several take-offs, the J-15 can be seen carrying the PL-12 medium range and PL-8 short range air-to-air missile in the middle and outer hard-points respectively. The PL-12 is an active radar-guided BVR missile and is similar to the Russian R-77 Adder and it is widely claimed that its seeker head is the same design as that of the R-77.4 The PL-8, on the other hand, is an IR guided missile and is believed to be based on the Israeli Python-3.5 In few other launches the aircraft can be seen taking off and landing with two YJ-83K anti-ship missiles slung under the centre-wing hard-point on each wing. -

Lockheed Martin F-35 Lightning II Incorporates Many Significant Technological Enhancements Derived from Predecessor Development Programs
AIAA AVIATION Forum 10.2514/6.2018-3368 June 25-29, 2018, Atlanta, Georgia 2018 Aviation Technology, Integration, and Operations Conference F-35 Air Vehicle Technology Overview Chris Wiegand,1 Bruce A. Bullick,2 Jeffrey A. Catt,3 Jeffrey W. Hamstra,4 Greg P. Walker,5 and Steve Wurth6 Lockheed Martin Aeronautics Company, Fort Worth, TX, 76109, United States of America The Lockheed Martin F-35 Lightning II incorporates many significant technological enhancements derived from predecessor development programs. The X-35 concept demonstrator program incorporated some that were deemed critical to establish the technical credibility and readiness to enter the System Development and Demonstration (SDD) program. Key among them were the elements of the F-35B short takeoff and vertical landing propulsion system using the revolutionary shaft-driven LiftFan® system. However, due to X- 35 schedule constraints and technical risks, the incorporation of some technologies was deferred to the SDD program. This paper provides insight into several of the key air vehicle and propulsion systems technologies selected for incorporation into the F-35. It describes the transition from several highly successful technology development projects to their incorporation into the production aircraft. I. Introduction HE F-35 Lightning II is a true 5th Generation trivariant, multiservice air system. It provides outstanding fighter T class aerodynamic performance, supersonic speed, all-aspect stealth with weapons, and highly integrated and networked avionics. The F-35 aircraft -

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress
Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress September 16, 2021 Congressional Research Service https://crsreports.congress.gov RL32665 Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress Summary The current and planned size and composition of the Navy, the annual rate of Navy ship procurement, the prospective affordability of the Navy’s shipbuilding plans, and the capacity of the U.S. shipbuilding industry to execute the Navy’s shipbuilding plans have been oversight matters for the congressional defense committees for many years. In December 2016, the Navy released a force-structure goal that calls for achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-ship goal was made U.S. policy by Section 1025 of the FY2018 National Defense Authorization Act (H.R. 2810/P.L. 115- 91 of December 12, 2017). The Navy and the Department of Defense (DOD) have been working since 2019 to develop a successor for the 355-ship force-level goal. The new goal is expected to introduce a new, more distributed fleet architecture featuring a smaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier of large unmanned vehicles (UVs). On June 17, 2021, the Navy released a long-range Navy shipbuilding document that presents the Biden Administration’s emerging successor to the 355-ship force-level goal. The document calls for a Navy with a more distributed fleet architecture, including 321 to 372 manned ships and 77 to 140 large UVs. A September 2021 Congressional Budget Office (CBO) report estimates that the fleet envisioned in the document would cost an average of between $25.3 billion and $32.7 billion per year in constant FY2021 dollars to procure.
