There is probably some truths to those incidents but the problem is when facts are incomplete then any conclusion can be clouded. Both incidents seem to imply that the sub was able to trail the carrier group. One of the reason why US subs are all nuclear powered is because conventional subs do not have the speed to keep up with a carrier group. How a Chinese conventional sub is able to trail a US carrier group is an issue I cannot reconcile with known facts. If the sub had simply lie in wait and was lucky to be in the pathway then it is possible but then the report of it successfully trailing would be incorrect. Do US carrier groups typically operate at speeds beyond conventional sub as a preventive operational maneuver I would not know.

Conventional subs cruise speed is somewhere around 5 knots while a battle group's cruise speed is more than 15 knots. A conventional sub's sprint speed may reach 20 knots, but it can only endure only 20 minutes before the batteries runs out and have to surface to snorkel in which it can be detected by surface radar.
So NO, a conventional sub Chinese or not can not trail a carrier battle group, BUT it can lay low and calculate the sea current and vector of the carrier group to slip in and out which really takes skill and knowledge with a little luck.
Japanese MSDF subs have been known to slip out of a carrier strike group during anti sub wars exercises using this technique after gaining kill marks.

Was the submarine detectes or not, I don't know and I don't want to debate about this. All I'm asking is exercices where the US successfully detect enemy submarines. As far I as searched, it happened during rimpac-2006 and in the hunter shark 2015 exercice. I would like more examples.

actually it's a good question if the USN is still able to find a sub in for example https://en.wikipedia.org/wiki/Lower_New_York_Bay

I haven't seen any recent picture of Burkes towing sonars, doing spring and drift if you know what I mean (now go ahead, tell me of their HMS, the Poseidons)

the OHPs were hastily retired

so that LCSs could, ehm, shine = filling the ports and feeding shipyards, the USN talking revolutionary transformational game changing capabilities

I guess the situation is even worse for minesweeping: there're 11 (eleven) Avengers left!!

America’s Déjà-Vu Withdrawal from Afghanistan https://www.defenseone.com/ideas/20...u-withdrawal-afghanistan/159758/?oref=d-river

Like Obama in Iraq, Trump wants to stop fighting before the war is done.

The president, facing what is likely to be a tough re-election campaign, is determined to withdraw U.S. troops and end the nation’s “forever war.” Despite his earlier promises that conditions on the ground will determine the policy, the political clock is clearly driving decision-making in the White House. Furling the American flag, claiming victory, and bringing the troops home will send a powerful election-season message.

At least President Barack Obama thought so when he pulled U.S. troops from Iraq at the end of 2011. As President Donald Trump eyes the exits in Afghanistan, it’s worth remembering the cautionary tale of our recent history in Iraq.

Certainly President Trump has made no secret of his desire to withdraw before next November. As August ended, Trump said he plans to bring home about 5,400 of the 14,000 American troops in Afghanistan. Speaking to Fox News Radio, the president said, “We’re going down to 8,600 and then we make a determination from there as to what happens…we’re bringing it down.”

The president spoke the day after Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, said that “I think it’s premature, I’m not using the ‘withdraw’ word right now,” adding that “we’re going to make sure…that Afghanistan’s not a sanctuary.”

A similar disconnect between the White House and the U.S. military colored discussions of a potential withdrawal from Iraq in 2011. The Obama White House, eager to end an unpopular war in Iraq as he ran for re-election, had little appetite for finalizing a Status of Forces Agreement that would have allowed for a continued U.S. troop presence beyond 2011. U.S. military leaders thought at the time that a total withdrawal was premature, unnecessarily risking the hard-won gains of years of fighting and nation-building.

Progress had been made in Iraq at great cost, but the situation was far from stable. The Iraqi government was showing its sectarian instincts, the training and equipping of Iraqi Security Forces was incomplete, and a sectarian civil war was raging next door in Syria. Leaving Iraq under those conditions created a vacuum that the Islamic State of Iraq and Syria (ISIS) quickly filled. To his great chagrin, President Obama was forced less than three years later to send U.S. troops back to Iraq under much less favorable conditions to keep the country from being overrun by the Islamist extremists of ISIS.

There are important lessons to be drawn from that debacle. First and foremost, it is perilous to fight a conflict on a political timetable. In retrospect, it’s also clear that the U.S. tutelage of the Iraqi Security Forces helped keep at bay the corrupting influences of cronyism, nepotism, and sectarianism. Once free of such U.S. pressure, Maliki indulged his sectarian instincts by placing incompetent loyalists throughout the Iraqi military command. When ISIS launched its offensive juggernaut in the summer of 2014, capturing nearly a third of Syria and Iraq and threatening Baghdad, the Iraqi Security Forces were either overrun or collapsed from the sheer incompetence, and in some cases treachery, of their chain-of-command.

Unfortunately, the Trump administration is adopting a similar blueprint for Afghanistan. Kabul similarly suffers from a weak central government. The Afghan National Security Forces are still heavily dependent on U.S. enablers. There is an ascendant terrorist insurgency mounted by the Islamist extremists not only of the Taliban, but also of a rising ISIS-Khorasan. And once again it is not conditions on the ground that are driving U.S. troop withdrawals, but rather a political agenda in the White House.

The Iraq experience strongly suggests that under such conditions, a premature U.S. troop withdrawal will create a power vacuum that the Taliban and fellow travelers in the global jihadist movement will be only too happy to fill, undermining the progress achieved over nearly two decades.

Even if America’s strategic objectives are limited to preventing the country from once again becoming the “Harvard University of Terrorism,” sufficient Special Operations, intelligence, and support forces will need to remain to conduct counterterrorism operations, backed by U.S. airpower and ISR (intelligence, surveillance and reconnaissance) capabilities. The 8,600 U.S. troops that President Trump says will remain in Afghanistan for the time being may not even be sufficient for that mission, given the rogue’s gallery of extremists groups that operate in the country, including the Haqqani network, Al Qaeda, ISIS and various Taliban factions.

There is certainly an argument to be made that after nearly two decades of America’s “longest war,” the situation in Afghanistan is simply hopeless. There’s little doubt that progress there is even further behind than Iraq circa 2011. Afghanistan lacks the latter’s oil revenue, literate and educated populace and modern infrastructure. There is also a high level of corruption and thus weakness in Afghan institutions across the board. Despite repeated U.S. efforts to end Pakistani support and sanctuary for the Taliban, the Pakistani intelligence services continue to use Taliban factions to exert influence on their weaker neighbor.

There has also been inarguable progress in Afghanistan. Despite irregularities, elections actually matter in the country. According to the Afghan Ministry of Higher Education over nine million children are currently enrolled in school, including 3.5 million girls and young women who were kept behind the veil and confined at home by the Taliban. Afghan soldiers and police continue to fight and die to prevent their nation falling once again into the Taliban’s totalitarian grasp, to the tune of more than 28,000 killed in action since 2015, according to the government.

The American public and body politic are understandably weary of the Afghan War. This week’s news that two NATO service members, including an American, were killed in a suicide bombing in Kabul tragically underscores the costs the United States and our allies continue to pay to keep that country from once again becoming a sanctuary for violent extremists. Secretary of State Mike Pompeo blamed that attack for the cancellation of the Camp David summit.

After that collapse, it’s not clear when the Trump administration will be able to reconstitute peace talks or craft the face-saving “peace deal” it so eagerly wants before next year’s election. We should at least be honest in recognizing that the deal, as currently constructed, will most likely surrender our Afghan allies to the tender mercies of the Taliban and like-minded Islamist extremists. We’ve tried that before in Iraq and the lesson is clear: just because one side quits fighting, it doesn’t mean the war ends.

I am not so concern about the technical aspect but the concept of operations. With flying drones, you either blow it out of the sky or spoof it to hijack the drone like what the Iranians did. What is stopping the Iranians or anybody else to sail along it, board it, disable the systems and hijack it? With a manned vessel you don't have such a problem to deal with.

USAF Shows Off B-1B With More Bombs, Hypersonic Missile

Source : Aerospace Daily & Defense Report Sept 9, 2019

U.S. Air Force officials have demonstrated a weapons bay modification that would expand the internal weapons capacity of the B-1B by 75% and allow the bomber to carry a hypersonic missile. The “expanded carriage” demonstration by the 412th Test Wing on Aug. 28 at Edwards Air Force Base, California, moves the bulkhead dividing the forward and forward intermediate weapons bays, which increases the length of the compartment to 269 in. from 180 in.
