日本准航母赴新加坡参展 却在众目睽睽下掉链子出丑

日本准航母赴新加坡参展 却在众目睽睽下掉链子出丑

2019年5月14日到16日,再新加坡樟宜展览中心以及海军基地,举办了IMDEX2019第12届新加坡国际海事防务展,这是亚洲最大规模的海事防务展会,不仅有多家防务企业齐聚新加坡,更有20多艘各国舰艇前往展示,我国的054A型护卫舰531号黄埔舰也前往参观。
此次还海事展上最瞩目的两艘军舰当属日本海上自卫队的准航母“出云”号直升机航母(日本称“直升机驱逐舰”),以及澳大利亚海军的“堪培拉”号两栖攻击舰。这两艘都是排水量超过2万吨的大型战舰,而且都具备很强的直升机搭载能力,区别是前者偏重反潜作战,而后者更专注于两栖作战,理论上这两舰都具备搭载垂直起降战机的能力,因此都被称作准航母。
不过在随后的公众开放中,日本这条准航母“出云”号却在关键时候掉链子了,闹了个不大不小的尴尬。作为日本海自的主力战舰,加上服役没几年,在对外展示时就出现这种问题,实在是不应该。

参观“出云”号的新加坡民众,注意其中穿迷彩的是新加坡国防军军人。此次“出云”号开放了一部分机库供人参观,另一部分要准备加班招待会,所以没有开放。

按照流程,下到机库参观后,人流应该跟随引导,称作舰岛左前方的舷内升降机上到飞行甲板进行参观,但在运载一波游客前,“出云”号的一号升降机却出现了故障,动弹不得。

在检查和试图排故失败后,升降机被围上了临时围挡,看来这个故障要等参观结束后花费时间去处理了。
“出云”号有两台升降机,出故障的是在前部的舷内升降机,该升降机占据了一部分机库空降,对于机库内调度有不小的影响,不过“出云”号主要搭载的是体型较小的直升机,所以才如此设计。可以看到这部舷内升降机三面都是舷墙,位于机库的最前方,使用的是铰链式升降系统。

“出云”号的另一台升降机,这是一台舷外升降机,不会占用机库空间,缺点是在高海况情况下使用会出现上浪的情况。当天由于要举办加班招待会,所以这部升降机所处位置并未开放,也没能近距离观察这台升降机。 (作者署名:啮花熊)


Japanese quasi-aircraft carrier went to Singapore to participate in the show, but in the eyes of the public, the chain fell out of the ugly
Japanese quasi-aircraft carrier went to Singapore to participate in the show, but in the eyes of the public, the chain fell out of the ugly
165

From May 14th to 16th, 2019, the Singapore Changi Exhibition Center and the Naval Base held the 12th IMDEX2019 Singapore International Maritime Defence Exhibition, the largest maritime defense exhibition in Asia, with not only a number of defense companies gathering. In Singapore, more than 20 ships from various countries went to the exhibition. China's 054A frigate 531 Huangpu Ship also visited.

The two warships that were most eye-catching at the Maritime Exhibition were the Japanese aircraft self-defense team's quasi-carrier "Izumo" helicopter carrier (known as "helicopter destroyer" in Japan) and the Australian Navy's "Canberra" amphibious assault ship. Both of them are large warships with a displacement of more than 20,000 tons, and they all have strong helicopter carrying capacity. The difference is that the former is more focused on anti-submarine warfare, while the latter is more focused on amphibious operations. In theory, both ships are equipped with vertical take-off and landing. The capabilities of the fighters are therefore called quasi-carriers.

However, in the subsequent public opening, Japan’s quasi-aircraft carrier “Izumo” lost its chain at a critical time, and it made a big embarrassment. As the main battleship of Japan's sea, plus several years of service, this problem occurred when it was displayed to the outside world. It should not be.

SH-60J anti-submarine helicopter in the "Izumo" hangar. This time the "Izumo" ugly happened in the hangar.

Visit the Singaporean people of the "Izumo" and notice that the camouflage is the Singapore Defence Forces. The "Yunyun" number opened a part of the hangar for people to visit, and the other part was to prepare for a overtime reception, so it was not open.

According to the process, after the visit to the hangar, the flow of people should follow the guidance, called the inboard lift on the left front of the island to visit the flight deck, but before carrying a wave of tourists, the No. 1 lift of the "Yiyun" There was a malfunction and it was impossible to move.

After checking and trying to fail the evacuation, the lift was surrounded by a temporary enclosure. It seems that this failure will take time to process after the visit.

There are two elevators in the "Izumo". The failure is the inboard lift at the front. The lift occupies a part of the hangar airborne, which has no small impact on the hangar dispatch, but the "Izumo" is mainly equipped. It is a smaller helicopter, so it is designed like this. It can be seen that the inboard lift is on all three sides of the bulwark, at the forefront of the hangar, using a hinged lifting system.

Another lift of the "Izumo" is an outboard lift that does not occupy the hangar space. The disadvantage is that it will be used in high sea conditions. Due to the overtime reception on the day, the location of the lift was not open and the lift was not closely observed. (Author's signature: Bear)

F-35B is crap of crap, because the vertical take off landing took away further more payload and performance from the already too problematic and junk F-35 family.

The is no arresting cables nor catapult nor jump ramp on Izumo - which are basically just designed to be a large host of anti-submarine helicopters. So they cannot use anything like F-35C which are tail-hooked and catapult launch designed. US Marine already crashed 1 F-35B before Japs crashed their own F-35A (land airbase version)

Probe finds F-35's first crash was caused by manufacturing defect, in revelation that could affect Japan plans to buy aircraft

Bloomberg, Staff Report








WASHINGTON - The crash of a U.S. Marine Corps F-35B that temporarily grounded the entire fleet of next-generation jets in 2018 was caused by a manufacturing defect in a fuel tube made by a United Technologies subcontractor, according to congressional investigators.
The defect “caused an engine fuel tube to rupture during flight, resulting in a loss of power to the engine,” the Government Accounting Office said last week in a report on major weapons systems that referred to the September crash in South Carolina. The Pentagon told the watchdog that it identified 117 aircraft — about 40 percent of the worldwide F-35 fleet at the time — with the same type of fuel tubes that had to be replaced.


The disclosure was the first official information about the crash since the Pentagon program office in late October issued a status statement while the Marine Corps was still conducting its investigation. United Technologies Corp.’s Pratt & Whitney unit “is fully responsible” for “the propulsion system and has the lead in working” the failure analyses, according to the statement at the time.
A spokeswoman for the Pentagon F-35 program office deferred comment to Pratt & Whitney, whose spokesman, John Thomas, said the company had no comment.
Marine Corps spokesman Capt. Chris Harrison said in a statement that the crash probe is continuing, and that the results will be released once complete. The marines have replaced all of the relevant fuel supply tubes and “we continue to strive each and every day to ensure the safety and readiness of our aircraft,” he added.
The F-35 is the Pentagon’s most expensive weapons program, at a projected cost of more than $428 billion.
The Sept. 28 crash of the F-35B near Beaufort, South Carolina, was the first in the two-decade old program’s often-rocky history of delays, cost increases and technical glitches. Although the pilot safely ejected, the incident prompted concerns about the aircraft, which is being built by and sold to an international consortium of U.S. allies, including the U.K, Italy, Australia and Turkey. Japan currently plans to procure a total of 147 F-35 fighter jets, 105 of which are expected to be F-35A models. The rest will be F-35Bs, which are set to be deployed on two Izumo-class warships that the Defense Ministry plans to convert into multipurpose aircraft carriers.
Last month, a Japanese F-35A crashed off Japan’s coast, with only portions of the jet’s wreckage found since then despite a monthlong search. The cause of the crash is under investigation. The jet’s pilot hasn’t been found. Japan has said that the crash would not affect its procurement plans, and it was unclear if the new revelations would spur any change.
The Pentagon program office said last year that “more than 1,500 suppliers are on the F-35 program and this is an isolated incident which is quickly being addressed and fixed. Safety is our primary goal.”
The defective part identified in the report provides operating pressure to the engine and fuel to the engine combustor.
Aside from the defect, Pratt & Whitney’s recent track record delivering engines on time has been spotty. Deliveries surged to 81 in 2018 from 48 in 2012, according to the GAO — yet 86 percent of those were delivered late, up from 48 percent in late 2017. The delays were due in part to an increase in the “average number of quality issues per engine” — 941 in 2018 against 777 a year earlier, the GAO said.
Pratt & Whitney told the GAO that “its late engine deliveries increased in 2018 partially due to a subcontractor that did not have all of the needed tooling in place to produce more F-35B engines,” according to the report.

Concept of Quasi-Aircraft Carriers are very misleading.

They don't even have 25% of a standard Carriers' functionality not just because they are too small & light displacement.

Because real carriers can take off and land many types of aircraft - Transporter + AWACs + Refuel Tankers + Spy plane, these are very big significant handicaps.

Without AWACs you have no advanced warning around yourself for your own survival, you also can not use AWACs to cover forward offensive operations which take place away from your own location. That means F-35B jets taking off from your quasi-carriers are just on their own, no AWAC to cover their ass! They gets shot-down very easily by enemies AWACs spotting them 1st before they can spot enemies fighter jets.

No refuel tankers meaning your F-35B taking off from here got SHORT RANGE or SHORT-LEG-HANDICAPPED.

No transporter planes meaning resupplies to yourself is very much limited to smaller helicopters capacities. These are usually fuel + ammunition / bombs used by your F-35B, which are very heavy.

Without catapult launchers the F-35B can have just a small fraction of take off weight = carrying less fuel and ammunition.

Short / vertical take off / vertical landing are much slower and higher risk of accidents and much more subjected to rough sea / strong wind @ sea. In bad conditions you become useless, if your F-35B took off at good weather and returned at bad weather, it may crash damaged or totally ruined or even ruin your carrier!

Hence Izumo type of quasi-carrier is way less than half a carrier, it is 25% or 20% of a normal carrier's combat capabilities only.

F-35B does not need a carrier to land after a mission. It can land in tian an men square. Right in front of china communist party hq.
Plus it will be used for defendive purposes. So anti aircrsft missiles mostly.very light.
