烏克蘭吐槽:美國無人機品質再這麼差 就找中國

據路透社12月21日報道,烏克蘭不滿意美國援助的價值數百萬美元的無人機,認為根本無法對抗東烏民兵的電子戰。甚至有一位專家直接稱呼那些無人機來自「石器時代」。烏軍顧問稱,如果美國人再不提供好的無人機,那麼就找中國人了。

美國近期提供了72架RQ-11「渡鴉」(Ravens)式無人機用於戰場偵察,但是一位烏克蘭軍方顧問認為,這些無人機是在太糟了。「如果我有決定權的話,我一定會退貨。」這位顧問用非常直白的語氣告訴路透社。西方國家一直指責俄羅斯給東烏民兵提供大規模軍事援助,如果沒有俄羅斯的軍援,東烏民兵不可能干擾那些無人機。

烏克蘭軍方發現,在戰場上,東烏民兵的裝備非常先進,其復雜程度遠遠超過了敘利亞、阿富汗還有伊拉克的武裝分子。

美國空軍已經向路透社承認了,「渡鴉」式無人機有根本性缺陷,無法對抗俄羅斯和東烏武裝的干擾。

美國軍方的匿名官員認為,俄羅斯給東烏武裝提供的電磁干擾裝備性能大幅提升,遠超戰爭剛爆發的時候。烏克蘭官方認為,美國在提供裝備上實在是太拖延了,等到裝備抵達的時候,敵人早就升級了自己的武器庫。目前美國只提供給烏克蘭軍隊非致命性武器。

在今年3月到7月之間,美國訓練了38名烏克蘭士兵操作此種無人機。烏克蘭空軍說,這種無人機被用來對抗東烏的「恐怖分子」。

但同時,烏軍顧問認為這種無人機航程糟糕,容易暴露,簡直就是一個靶子,根本無法完成任務。而另外一位專家認為,這款無人機簡直是制造於「石器時代」(Stone age)。

自烏克蘭危機爆發之後,美國已經提供了超過6億美元的軍事援助,而「渡鴉」無人機總價值約1200萬美元。

同時,烏軍顧問稱,如果烏克蘭一直無法獲得自己想要的無人機,烏軍可能主動把訂單交給中國、捷克或者其他國家,他們能夠生產更加先進的無人機,而且每一架只賣2萬到2.5萬美元。而現在的「渡鴉」式無人機每架要花16.7萬美元。

Exclusive: U.S.-supplied drones disappoint Ukraine at the front lines

By Phil Stewart | WASHINGTON

Millions of dollars' worth of U.S.-supplied drones that Kiev had hoped would help in its war against Russian-backed separatists have proven ineffective against jamming and hacking, Ukrainian officials say.

The 72 Raven RQ-11B Analog mini-drones were so disappointing following their arrival this summer that Natan Chazin, an advisor to Ukraine's military with deep knowledge of the country's drone program, said if it were up to him, he would return them.

"From the beginning, it was the wrong decision to use these drones in our (conflict)," Chazin, an advisor to the chief of the general staff of Ukraine's armed forces, told Reuters.

The hand-launched Ravens were one of the recent highlights of U.S. security assistance to Ukraine, aiming to give Kiev's military portable, light-weight, unarmed surveillance drones that were small enough to be used widely in the field. They are made by AeroVironment.

But they appear to have fallen short in a battle against the separatists, who benefit from far more sophisticated military technology than insurgencies the West has contended with in Afghanistan, Iraq or Syria.

Whether President-elect Donald Trump's administration might seek to provide Kiev anything more robust, however, is unclear, given his stated desire to improve ties with Russia and prioritize the fight against Islamic militants. U.S. restrictions on technology exports could also limit new aid.

The Air Force command of Ukraine's armed forces acknowledged to Reuters that the Ravens supplied by the United States had a fundamental drawback: Russia and the separatist forces it supports can intercept and jam their video feeds and data.

"The complex is analog, therefore command channels and data are not protected from interception and suppression by modern means of electronic warfare," it said.

U.S. officials, speaking on condition of anonymity, acknowledged that Russia's electronic warfare capabilities were far more sophisticated than thought when the conflict began and that both the U.S. and Ukrainian militaries were adapting.

Asked about Ukraine's reaction to the Ravens, one official said it took a considerable amount of time for the drones to reach Ukraine and that by then "they were much less effective than they would have liked, than we would have liked."

AeroVironment referred questions from Reuters about the Raven contract to the U.S. Army.

The U.S. Army told Reuters it still uses Ravens but has upgraded to digital versions.

"STONE AGE"

Some 38 Ukrainian students were trained at Redstone Arsenal in Alabama on how to operate the drones between March and July this year, a U.S. Army spokesman said.

Ukraine said it distributed the Ravens across the services and gave one batch to the Zhytomry Military Institute for training purposes.

There were mixed accounts on how much the Ravens were being used in Ukraine, which saw Crimea annexed by Russia in 2014 and which has been fighting Russian-backed separatist forces in the east. Nearly 10,000 people have died in the conflict.

The Air Force command of Ukraine's armed forces said they were being used in the "Anti-Terrorist Operation" zone, including in combat situations.

One Ukrainian official, however, speaking to Reuters on condition of anonymity, said that although drones were being used in the zone, they were not employed on the front lines.

Chazin said they were largely in storage and called them a vulnerability, allowing the enemy to see Ukrainian military positions and, when it wanted, easily take them down. They had short battery life and were unable to reliably fulfill the key mission of gaining intelligence on artillery positions, he said.

"(Analog) basically puts you back in the stone age of the UAVs," said James Lewis, director of the strategic technologies program at the Center for Strategic and International Studies, using an acronym for Unmanned Aerial Vehicles, or drones.

"I'm not being critical of the Raven. I love the Raven ... But it's a cheap, disposable UAV. And for more intense conflict, that may not cut the ice anymore."

TRUMP'S UKRAINE POLICY?

The drones, along with other U.S.-supplied items like radar, first-aid kits, night vision and communications gear, fit into President Barack Obama's strategy of providing non-lethal military assistance while focusing on sanctions and diplomacy to end the war.

Within that context, the miniature drones, even though small, were a noteworthy element of the more than $600 million in training and equipment that the United States has provided Ukraine so far. Ukraine pegged the Raven program's value at over $12 million.

How Trump might alter U.S. support remains unclear, particularly given cabinet picks that include retired Marine General James Mattis, who has been vocal about his concerns about Russia and was nominated to become U.S. defense secretary.

Some of the most prominent Republican lawmakers in Congress have called for Ukraine to receive lethal arms.

"If anything, it creates a new opportunity," said Luke Coffey at the Heritage Foundation, a conservative Washington think-tank.

Ukrainian officials have sought to put a brave face on Trump's election, downplaying comments on the campaign trail that included appearing to recognize Crimea as part of Russia and contemplating an end to U.S. sanctions on Russia.

Ukraine's President Petro Poroshenko is expected to visit Washington next year, and U.S. assistance is sure to be high on his agenda.

Topping Ukraine's wish list are Javelin anti-tank missiles made by made by Raytheon and Lockheed Martin. The top U.S. military officer in Europe, General Curtis Scaparrotti, told a Senate hearing this year "there's a requirement for an anti-tank weapon, like Javelin."

One of the U.S. officials cautioned about limitations on America's ability to export drones that can evade Russia's electronic warfare capabilities.

That could leave Ukraine's military to continue building drones from commercially available technology. It now assembles them from components supplied by firms in countries such as Australia, China and the Czech Republic for only $20,000 to $25,000 apiece, Chazin said, and they are more advanced than the more pricey Ravens, which are often funded from private donations.

請支那免費提供無人機啊

烏克蘭之前沒賣這麼多先進武器給中國,中國武器能發展(X),複製(O)這麼快嗎?
現在還敢宣傳 遼寧號航空母艦 多強多好,也不想像是如何來的,真是他媽的諷刺...

面對烏克蘭問題連屁都不敢放就怕得罪俄羅斯,就別稱自己是大國勃起 乖乖當俄羅斯小老弟就好~
