1/USS Carney Shot Down More Missiles, Drones Over Longer Period

Carney's engagement in the #RedSea highlights some issues for the @DeptofDefense & @USNavy in modern naval warfare.

thedrive.com/the-war-zone/u…
2/It is reported that Carney engaged 4 cruise missiles and up to 19 UAV drones with their SM-2 standard missiles.

Hitting Israel from Yemen is over a thousand miles and these fit the parameters of Iranian cruise missiles.

iiss.org/online-analysi…
3/UAV drones traveling that far is also a major concern, but there have been examples of Iranian drones being used in Ukraine by Russia.

It is reported that Carney's action took place over several hours.

iranprimer.usip.org/blog/2023/mar/…
4/The engagement of 4 cruise missiles and 19 UAVs with SM-2s presents a concern regarding the ability of a modern warship to remain in the fight due to ammunition expenditure.

Carney has 90 vertical launch system cells (VLS). 23 targets would require multiple standard missiles. Image
5/If Carney is the sole US destroyer presence in the area, then an shooting down 23 missiles/UAVs may have greatly depleted if not exhausted her armament; known as going Winchester. Image
6/In the past, the @USNavy would have destroyer tenders forward deployed to not just provide maintenance for ships, but to reload warships - principally destroyers. But the US decommissioned its last destroyer tender in 1996. Image
@USNavy 7/While the @usnavy has prioritized the ability to reload VLS cells, the nature of the tubes require the ships to be in calm water at anchor or pierside and it is time consuming. As of yet, no method has been developed to reload VLS at sea.

defensenews.com/naval/2023/03/…
@USNavy 8/This event should give concern about potential swarm attacks on ships and the limitations that modern vessels have to defend themselves against such threats.

While these weapons were targeted at Israel and not Carney, it is still a lesson that needs to be driven home.

10/Some great discussion on this topic.

We don't know the load out of Carney's 90 VLS cells. SM-2s take up an individual cell, but she is also an Ballistic Missile Defense (BMD) ship so may have SM3s & SM6s onboard.

Evolved Sea Sparrow Missiles (ESSM) are quad packed in cell.

11/The impetus of the thread is what happens when a VLS armed ships expends its ordnance and possibly depletes its main long range anti-air weapons.

While we have reloaded missiles at sea in the past, these were launchers with magazines, largely. Image
12/We have loaded VLS at sea and there were plans as far back as the 80s to outfit Burkes with that capability but the logistics of removing and returning spent canisters became an issue.

13/Others, such as @cdrsalamander have been highlighting this issue for years

1/In 1936, the US signed into law a Merchant Marine Act that sought to replace the fleet built by the US Shipping Board from 1917-22.

With the rise of tensions in Asia & Europe, the US realized that it was overly dependent, once again on foreign shipping to move its commerce. Image
2/Included in the act was Title VII which allowed companies in international trade to receive differential subsidies for the construction and operation of their ships.

The hope was to restart commercial shipbuilding, but the height of the Great Depression made this difficult. Image
3/To jump-start shipbuilding, Title V allowed the government to initiate shipbuilding with the leasing of ships to commercial operators. The plan was to build 500 ships over ten years.

The first 50 ships were built to four distinct designs, each with national defense features. Image

1/Everyone is saying US ports are empty, but for most of these observers, this is their first time looking at the ports and ship data.

Here is some context:
▶️US Container Import Volumes are tracking on the high side for Q1, with only 2022 being higher.
▶️West Coast Mexican & Canadian ports just exceed the capacity of @PortofLA by itself, so the US needs cargo to flow into its ports.
▶️The four biggest US ports are extremely dependent on China imports:
@PortofLA 62%
@PortNYNJ 27%
@portoflongbeach 65%
@GaPorts 35%

It takes about 2-3 weeks to sail from East Asia to the West Coast about 4-6 weeks. With the tariffs going into affect on all cargo loaded after April 9, those ships have arrived on the West Coast and they will be on the East/Gulf Coast mid-May.Image
Image
Image
Image
2/As I have stated previously:

▶️The idea that US ports are empty or the ships are not sailing to the US is false as in this video.

▶️What is happening is the data for the ports are showing the dip in imports, with @PortofLA showing a 35% drop in Week 19 (May 4-10).

▶️The thing to watch is the container volumes departing China for the US and the slight uptick at the end of April.

The 145% is extreme, but is the mark up enough to deter companies from ordering inventory to replace everything that came in during Q1? Also, is there even a suitable alternative to the Chinese manufactured goods and what will be the overall cost differential, especially for low-cost, but high-mark up items?
Image
Image
3/The question is how does industry react? @FreightWaves and @FreightAlley asked 20 firms across four sectors:

▶️Automotive and Transportation
▶️Retail and Consumer Goods
▶️Technology and Electronics
▶️Industrial and Manufacturing

They range from revised financial guidance and pausing productions; to @Walmart resuming some Chinese suppliers; shifting productions to other countries; and some like @whirlpoolusa see them as a competitive advantage.

1/Everyone has to be careful about misreading shipping data. This chart from @MarineTraffic shows normal density for containerships and shows icons for all vessels destined for the US. Image
2/The data from the @PortofLA is showing that cargo for this week (which is coming in before the Apr 9 loading date) is expected to be 56% over the same week last week. This is on top of a record Q1 with a lot of front loading. Image
@PortofLA 3/The Blank Sailings everyone is hearing of is currently at 10% with 75 sailings out of 718 between 28 April and 1 June. These cancellations are not unusual; in May last year there were 19 blank sailings to the West Coast and 22 in May. Image

1/Great podcast with @CavasShips, @CSSProvision & @brentdsadler.

One of the key takeaways is this misguided concept set forth by the former SecNav and CNO of @USNavy that we lack shipbuilding capacity in the US.

This is FALSE!
2/First, the issue is the lack of contracts with the current yards and the fact that nearly all shipyards have one sole customer...the @USNavy. Therefore they have to be burdened with a sea of @NAVSEA rules and inspectors. Image
3/Globally, we have seen a reduction in global shipbuilding capacity from 700 yards in 2007 to 300 in 2022. That is a reduction of ship construction capacity from 2000 ships to 1200. Plus, this capacity is focused on 9 companies in China, Korea & Japan.

1/The damage to USS Harry S Truman (CVN-75) has me thinking along the same lines as when USNS Big Horn (T-AO 198) ran aground off Oman and left the Lincoln battlegroup without an oiler.

What if Truman was damaged in battle and what is the historical comparison that the US Navy can look towards?
2/Much like I compared Big Horn's loss to that of USS Pecos in January 1942, the situation early in the Pacific War may provide a good example for the @USNavy for a potential peer-to-peer conflict in the Pacific.

gcaptain.com/for-want-of-an…
3/At the start of the Pacific War in December 1941, the US Navy had 3 carriers in the Pacific with another 3 in the Atlantic (not counting Ranger). The US faced off against 6 Japanese fleet carriers as brought to bear off Hawaii.

How did the US carriers fare in the first half of the war?Image

1/I don't think the author of this article understands how the ocean can be used to fight the #LosAngelesFire #PalisadesFire.

First, what is needed is water to supply fire engines and tenders (tankers). When the fires burned through residential and commercial areas, the water pipes are opened and every structure pulls on the system.
2/Water systems are designed to operate off reservoirs, elevated tanks, pumping stations, or a combination of all. Normally, pumping stations fill elevated tanks during low-consumption periods. The tanks & reservoirs use the weight of the water and gravity to push water through the pipes.Image
3/As was noted by the director of @LADWP, the tanks were drained due to consumption and as fires opened lines.

The system pumps could not refill the tanks & charge the pipes. This resulted in the loss of pressure on all the hydrants, which has happened in past fires. Image
