Early this morning Iranian air defense shot down a U.S. high altitude reconnaissance drone:

DUBAI (Reuters) - Iran’s elite Revolutionary Guards have shot down a U.S. “spy” drone in the southern province of Hormozgan, which is on the Gulf, the Guards’ news website Sepah News said on Thursday.State news agency IRNA carried the same report, identifying the drone as an RQ-4 Global Hawk.

“It was shot down when it entered Iran’s airspace near the Kouhmobarak district in the south,” the Guards’ website added.

A later statement by the IRGC detailed the incident:

The American UAV took off from an US base in the south of the Persian Gulf at 00:14 am today morning and contrary to aviation laws, it shut off all of its introduction equipment and proceeded from the Strait of Hormuz to Chabahar with complete secrecy.The unmanned aircraft while returning to the west of the region towards the Strait of Hormuz, violated the territorial integrity of the Islamic Republic of Iran, and start collecting information and spying.
At 4:55 am, when the aggressive UAV entered our country’s territory, it was targeted by the IRGC air force and was shot down.

The U.S. says that the drone was a MQ-4C Triton, the navy variant of the Global Hawk type that is specialized on Broad Area Maritime Surveillance (BAMS). It claims that the drone was in international airspace when Iran's Revolutionary Guard shot it down.


(Interestingly no MQ-4C is supposed to be in the Middle East. The deployment must have been secret. Update: This specific drone seems to have arrived in Qatar only five days ago. Additional details are discussed here. /update)

The incident is another piece of evidence that Trump's "maximum pressure" campaign against Iran now works against him.
Trump allegedly told his staff to stop talking up war on Iran:

Two senior officials and three other individuals with direct knowledge of the administration’s strategy in the region tell The Daily Beast that the president has asked officials to tone down their heated rhetoric on Iran ...

Trump does not want to open a military conflict with Iran. But he is already waging a brutal economic war against Iran and the country is pushing back. Trump wants negotiations with Iran without first lifting his sanctions against it. Iran rejects that.
It no longer matters what Trump wants. Iran has achieved escalation dominance. It can cause a myriad of incidents that force Trump to react. He can either launch a hot war and thereby risk his reelection bid, or he can cut back on the sanctions that hurt the Iranian people. If he does not do either, more pinpricks will follow and will over time become more costly.

Abas Aslani @AbasAslani - 7:29 UTC · 20 Jun 2019#Iran's #IRGC commander Salami: Shooting down the US drone had a clear & strong message i.e. we'll react strongly against any assault to the country. Borders are our red line. We are not after a war with any country, but we are ready for war. Message of today's incident was clear.

The loss of the Global Hawk drone is significant. These huge birds, with a wingspan larger than a Boeing 737, are considered strategic assets. They were built as replacements for the infamous U-2 spy planes. They carry highly classified sensors and cost more than $120 million a piece.





This loss can certainly be attributed to Iran. But to blame Iran for it the U.S. will have to prove that its drone did not enter Iranian air space. Only two days ago the Federal Aviation Authority issued a warning for aircraft flying in the area.
U.S. drones have violated Iran's sovereign airspace many times. In 2011 Iran acquired a stealthy RQ-170 drone which had flown in from Afghanistan by manipulating its command signals. In 2012 Iran took down another U.S. drone, a Boeing Scan Eagle, that had flown in from the Persian Gulf. Many other U.S. drones were shot down over Iranian territory:

In January [2011], Iran said it had shot down two conventional (nonstealth) drones, and in July, Iran showed Russian experts several US drones – including one that had been watching over the underground uranium enrichment facility at Fordo, near the holy city of Qom.
...
Secretary of Defense Leon Panetta told Fox News on Dec. 13 that the US will "absolutely" continue the drone campaign over Iran, looking for evidence of any nuclear weapons work. But the stakes are higher for such surveillance, now that Iran can apparently disrupt the work of US drones.

The Persian cats are by now well trained in anti-drone measures.

How will Trump react to this incident? President John Bolton will demand military action against Iran as revenge for the shoot down. He will surely also press for sending more troops to the Middle East.


Trump may again play down the incident, like he recently did with the tanker attack which he called "very minor". But the war hawks in the media and Congress, and Iran, will put more pressure on him. More incidents would surely follow.


Trump has a way out. He could issue sanction waivers to allow China, Japan, South Korea, India and others to again import Iranian oil. It would take the "maximum" out of his now failed "maximum pressure" campaign and could be a way to move towards negotiations.

Update 2:00 PM

The Pentagon just held a very short press conference. Via telephone Lt General Joseph T. Guastella from the U.S. Central Command made a very short statement. No questions were allowed.


He said that the drone was in international airspace at high attitude and "34 kilometer from the nearest point of the Iranian coast" when it was shot down.
That is trickery, or if you will trigonometry.


High attitude means that the drone flew at a height of around 60,000+ feet or 20 kilometer. It it would have flown directly over the Iranian coastline it would have been "20 kilometer from the nearest point of the Iranian coast".

The 34 kilometers is the length of the hypotenuse AC of the right-angled triangle. The hight is the opposite AB. What we have to find is the length of the adjacent BC.


? = square root of ( 34 x 34 - 20 x 20) = 27.5 kilometer
National maritime zones and national air zone are measured in nautical miles: 27km / 1.852 = 14.85 nautical miles.


The length of the adjacent BC, i.e. the legal distance of the drone to the Iranian coast, was 14.85 miles. That is at least according to the CentCom talking head.
Iran's national maritime zone, which equals the national airspace limit, is 12 nautical miles from its coast. The U.S. navy claims that its drone was a tiny bit further away.

This map was shown during the Pentagon briefing.


Now compare it with this map that shows the maritime borders of Iran, Oman and the UAE in the Straits of Hormuz.


There is no international airspace in the tightest, northern part of the Straits of Hormuz. There is only the national airspace of Iran and Oman. If what the CentCom map shows is the correct location of the drone, which had come from the south, it was in the mid of a blind alley of international airspace flying towards its end.


The drone was the RQ-4N BAMS-D. It was the U.S. navy owned prototype for the new MQ-4C Trition type of the Global Hawk that is currently build. The RQ-4N was unique. It used an old Global Hawk frame packed with new electronic equipment. It was used as the test bed for the gigantic data hoover that the Triton will be. But it was also a piece of equipment that was hard to maintain and that had served its purpose. The first of the hew drones will be delivered this summer. The RQ-4N was arguably expandable.


The Iranian IRGC says that the drone had switched off its transponder shortly after take off. A look at the usual live air traffic sites confirms that the drone was not tracked by the civil aviation systems which monitor transponder signals.


The U.S. airforce, which each day flies reconnaissance missions near potentially hostile countries, always keeps its transponders on. The transponder signal demonstrates that it has no hostile intent. It prevents accidental air defense engagements. It also allows it to prove that it stays outside of foreign national airspace.


The U.S. has threatened Iran with war and regime change for some 40 years. There is currently a crisis caused by Trumps violation of the nuclear deal with Iran. If the CentCom claim is correct the Navy drone flew extremely near to Iran's border, seconds away from entering it, in a way the Iran had reason to interpret as ould well interpret as hostile. Iran released a video that supposedly shows the shoot down.


Iran says that the drone entered Iranian airspace. I find that to be likely correct. CentCom is not known for telling the truth and the list of proven hostile drone entries into Iranian air space is quite long.


Trump just held a press conference in the Oval Office. He seemed to play down (vid) the event. He empathized that the drone was unmanned. He said he had "a big, big feeling" that "someone made a mistake", that "some Iranian general probably made a mistake". That means that he does not accuse the government of Iran of the shoot down, but some lowly grunt who "might have made a mistake."


That statement gives him room to avoid a large retaliation.

Someone made a mistake? So what.


As an example of what it costs sometimes at key times this is what happened when I tried to post this article,  Of course I believe in the Theory of Infinite Coincidence!
