A scenario that upends conventional wisdom

 

Could this happen....This piece was put together back in 2012. The technology has only improved since then. While this is an alternative analysis of possibilities in the PACOM area. this article brought my memories back

But before that some recent articles....

China Enters the UUV Fray – The Diplomat



"HSU001 is a Large Displacement UUV (LDUUV), roughly analogous to the U.S. Navy’s own LDUUV, “Snakehead,” which is designed for missions such as intelligence preparation of the environment (IPOE) and anti-submarine warfare (ASW). At approximately 7 meters long, it is less than half the size of “Orca,” the U.S. Navy’s Extra Large UUV (XLUUV) which will be pier launched and is designed for complex, long-distance missions, including the delivery of specialized payloads such as mines, seabed sensors, and small UUVs. While HSU001 lacks the capacity for such large-scale payload integration, it may be capable of deploying micro UUVs or other sensors, or carrying payloads via external hardpoints. While it lacks adequate energy stores to transit thousands of nautical miles like Orca, it will likely be capable of long-endurance missions lasting several weeks to several months"

And the below is the fictionalized story that preceded a research paper on AUV/UUV's.

written about a decade ago...and yes It could happen


The Stennis Carrier Strike Group (CSG) had been tasked to deploy to the South China Sea in order to demonstrate the U.S resolve regarding Taiwan. The new leadership in Taiwan had recently begun the political maneuverings necessary to put a vote of independence towards the Taiwanese electorate. The result was that the People Republic of China had issued veiled threats. 

This had resulted in the Stennis CSG deployment. By December 2022 such deployments had 50 years of history and had become routine. 

As the CSG approached the South China Sea it was steaming at condition III. In this state roughly thirty percent of the crew would be on watch. From this condition it would be possible to rapidly transition to either condition II, a variant of General Quarters or to General Quarters itself.

During the extensive work ups to prepare for deployment the officers and crews of the Stennis CSG had focused primarily on the Air Warfare. In particular, the CSG trained extensively to the Air threat posed from the Shi Lang 1 (formerly the Russian Varyag). 

However, the CSG also trained extensively against the threat posed by China's long range Anti-Ship missiles.

The first threat, the Shi Lang had recently left homeport and commenced flight operations in the South China Sea. For the later threat, PACOM commanders had been wringing their hands since these missiles had first reached initial operational capability in late 2012 . There would be three more  carriers either operational or in the water by 2021. While the CSG commander was prepared for both - he had a nagging worry. The training and workups had been so Air Warfare centric threats that Undersea Warfare training had suffered

Several hours before sunrise an order was transmitted via a recently launched Chinese commercial satellite that ostensibly beamed Chinese language programming to Chinese viewers on mainland China. The signal reached a communications buoy that surfaced every three hours

From there, the order was relayed to the vast undersea network before ultimately reaching a swarm of Unmanned Underwater Vehicles. 

These vehicles had been deployed by the air  a week ago using a means similar to the Snowflake Air Deployment Systems developed at the United States Naval Post Graduate School in the late 2000’s. 

Since that time they had been positioning themselves in the path of the CSG by relying on cueing from the distributed remote sensing, mobile underwater networks and more conventional sensing networks employed by China. Much in the same way German U boat packs were able to position themselves in the way of Allied convoys based on intelligence and Airborne sightings in WW II

The swarm began to close on the CSG undetected by the CSG's equipment. They were just too quiet.

Just before sunrise, the AEGIS class Guided Missile Destroyer USS Preble suffered catastrophic damage at frame amidships. Ten minutes later, despite the best damage control efforts, she rolled over and sunk. 

Nearly simultaneously her sisters USS Decatur and USS Howard were similarly damaged. 

The two remaining destroyers and their much vaunted AEGIS weapons systems were off line or effectively destroyed. 

The result was catastrophic for the CSG. The Aircraft Carrier Stennis, was now essentially defenseless from a coordinated air attack with her AEGIS escorts offline and fighting to stay afloat

The scene above was witnessed, fathoms underwater, by one of the many tethered listening devices. It evaluated the reduced signature to noise ratio and the sound of the USS Preble breaking up. Its primitive logic commanded it to surface and transmit a brief message to PRC Naval HQ. 

This message confirmed to PRC leadership that USS Stennis was now deprived of its Air Defense Umbrella. 

With the escorts intact the probability of hit - and kill – by Anti Ship Cruise Missiles had been evaluated as marginal. 

With the escorts removed from the equation the Carrier that equation was drastically changed and the CSG was far more vulnerable to attack from surface and land launched Anti-Ship Missiles.

Approximately thirty minutes later the first land based Anti-Ship Cruise Missiles homed in on the USS Stennis. 

The distributed underwater surveillance system, and associated systems provided Over the Horizon Targeting. 

This attack resulted in the USS Stennis suffering what would be termed catastrophic mission kill. 

Her flight deck was holed; aircraft on fire and vital communications systems were off line. While the carrier would stay afloat the damages would take months in a dedicated repair yard.

However, she would not get that chance. As she steamed slowly east she and her remaining escorts, were struck by a group of Houbei Fast Attack Craft (FAC) 4 . 

Each of these craft fired an initial shoot shoot look salvo of 4 YJ-83 Anti-Ship Cruise Missiles from standoff range at the now defenseless carrier. 

Minutes later the same ships fired their remaining 4 missiles and quickly turned changed course at high speed to return to their homeport

This day in December 2022 would be the worst loss the U.S. Navy had experienced in decades. Deprived of the protection of the U.S CSG Taiwan was unable to repel combined Air and Sea attack by the PRC two days later.  And the US was unable to surge assets to support

The PRC quickly gained full control of that country and the promise of U.S. protection was severely tarnished the world over. 

More importantly, China had always been viewed as a land power however China had now demonstrated the capacity to deny the much vaunted U.S Military access to most of the PACOM area of operations and established herself as the de-facto maritime power in the South China Sea.

Below is the research that backed the paper up...wont bore you with the actual paper as it would probably need a bunch of updating given the advances in battery and communications tech in the last decade
