To no one's surprise, it took around 24h for the secret information that was referenced in the parliamentary debate on Taurus to leak. This information pertains to the processing power required for inputting & processing targeting data. Some thoughts: 1/10
t-online.de/nachrichten/de…
The notion that the Taurus targeting process necessitates large amounts processing power and data is not a new or secret revelation. Broadly speaking, there is a "simple" and an "extended" Taurus mission planning protocol. The two are also referenced in the leaked call. 2/10
"Simple" mission planning typically involves waypoint navigation using GPS. While this simplifies the planning process, it also renders Taurus more vulnerable to countermeasures and reduces accuracy. 3/10
"Extended" mission planning is more complex. Here you integrate topographical data for TERCOM, pictures for image-based navigation, data on enemy air defense positions, and more detailed models of your target. 4/10
The probability of Taurus reaching and eliminating its target rises with the complexity of the mission planning process, as discussed in the leaked call. The greater the intricacy of the targeting process, the higher the level of training required by the Ukrainians. 5/10.
Keep in mind that this kind of extended mission planning was feasible back in the early 2000s, so it doesn't require supercomputer-level technology. It's also entirely achievable to store the necessary data separately from the physical data processing machines. 6/10
In the leaked call, officers discussed how Storm Shadow mission planning is conducted through "reach back." This likely refers to accessing some data stored in the UK. This indicates that the UK helps Ukraine perform an extended mission planning process in Ukraine. 7/10
Does this change anything? Absolutely not. Ukraine is fully capable of developing its own data processing infrastructure and obtaining its targeting own data, which they probably already have. Let's not forget that Ukraine also has its own cruise missile program. 8/10
The fact remains, that if there was political willingness to allow Ukraine to use Taurus, the government would find a solution that minimizes and potentially prevents any direct Bundeswehr involvement in Ukraine. The key issue is the lack of political will. 9/10
This has been a savvy political move by the SPD. They invited high-ranking officers to a "secret" meeting where reporting was not allowed, talking about the scarcity of German equipment. It's no surprise that this tactic influenced some uninformed members of parliament. 10/10
Many thanks to @John_A_Ridge for reminding me that the United States developed a mission planning system for Tomahawk in the 1990s that can fit inside a van lol. Image

Hie liegt @winkelsdorf falsch. Die Bundeswehr hat 600 Taurus KEPD 350 bestellt und bekommen. Es gibt keinen Taurus MP. Dieser wurde geplant, aber letztlich nie entwickelt, da es keinen Kunden gab (wie für andere geplante Versionen). Ein kurzer Thread. 👇 1/5
Taurus ist modular ausgelegt, um auf potenzielle Fähigkeitsforderungen von Kunden reagieren zu können. Es gibt aber keine modularen Taurus im deutschen Arsenal (oder in irgendeinem anderen). Image
Ich denke ein Teil der Verwirrung stammt von dieser Powerpoint aus dem Jahr 2008. Da wird der KEPD 350 als Basismodell angegeben. Die ganzen anderen Modelle sind Konzepte, existieren aber nicht. Darunter eben auch der Taurus MP. 2/5 Image

Here's a thread discussing the range of Storm Shadow/SCALP-EG. Some have asked me to explain why I believe the range of Storm Shadow/SCALP-EG supplied to Ukraine is comparable to that of Taurus (500+ km), and why Ukraine has yet to attack the Kerch Bridge. 1/11 Image
Two relevant variants of Storm Shadow/SCALP-EG have been developed over the years. The baseline model with a range of around 550 km and an export version, the 'Black Shaheen' with a range of 290 km. Apart from their range difference, both missiles are identical. 2/11
The Black Shaheen was initially developed for export sale to the UAE and has sparked controversy. In order to comply with MTCR guidelines, which restrict the sale of missile systems with a range exceeding 300 km to non-MTCR members, France reduced the range of the missile. 3/11

Once again, @WAJKoenitz is proving himself as someone who has no understanding of Taurus and missile systems in general. Suggesting that Taurus, or any modern cruise missile, has a CEP of 10m is the dumbest shit I've read on this app today. 1/9 Image
CEP (circular error probable) is a probabilistic method used to evaluate accuracy. It represents the smallest radius of a circle within which 50% of projectiles are expected to land. A 10m CEP indicates that 50% all shots fired fall outside a 10m radius of the target. 2/9
If this was the case for Taurus:
1) Taurus would fail in its primary purpose (engage targets with pinpoint accuracy)
2) Would never have been accepted by the 🇩🇪 armed forces
3) Would have no export customers

My god, I expect 🇰🇵 cruise missiles to have a lower than 10m CEP. 3/9

This will be my final comment on the Taurus issue, as I'm growing weary of repeating the same points.

Unfortunately, many in 🇩🇪 still view Taurus as optional, when in reality it is not. Without a replenishment of long-range strike weapons, 🇺🇦 will inevitably face depletion. 1/4
At a consumption rate of 30-50 Storm Shadow/SCALP-EG per month, Ukraine will run out by the end of 2024.

Yes, the consumption rate could drop further, but Ukraine is already struggling to integrate LRS usage into a coherent missile campaign at the current rate. 2/4
A further decrease in consumption will lead to strikes becoming even more isolated and less influential in determining outcomes at the theater level.

This will also lessen the threats faced by 🇷🇺 rear units, increase 🇷🇺 logistical flexibility, and free up air defense assets. 3/4

Because I keep receiving comments like these, here's a comprehensive thread explaining why I don't believe Taurus deliveries are being held up by the 🇺🇸. My position is based on the available data points and considering both alternatives (🇩🇪 at fault vs. 🇺🇸 at fault). 👇1/7
1. Taurus does not include highly sensitive American technologies.

Two significant components in Taurus of US origin are the Rockwell Collins GPS receiver with a Selective Availability Anti-Spoofing Module (SAASM) and the Williams International P8300-15 Turbofan engine.

This is the reason why Germany would require US approval before delivering Taurus to Ukraine. However, these technologies are not considered highly sensitive.

In the past, turbofan engines were considered a proliferation risk. However, with increased access to this technology, these concerns have largely subsided. Currently, every US adversary has access to these types of cruise missile engines.

I don't believe it would have any significance, but it may be worth noting that the engine utilized in the Taurus missile differs from the F107 turbofan engine employed in JASSM-ER. Consequently, Russia could not draw any conclusions regarding propulsion of U.S. long-range strike weapons.

When we consider the GPS receiver, it is evident that the United States has already sent numerous jamming-resistant GPS receivers in Ukraine. This technology has been notably utilized in GMLRS artillery rockets. As such, this technology is, in theory, already at risk of falling into Russian hands.

Also, the receiver only plays a role if Ukraine were to receive upgraded Taurus from Germany's operational stock. If it receives only recertified older ones than the upgraded American receiver would not be not included.
2. Alliance dynamics outweigh coalition politics.

If you've been following the Taurus debate, you're aware that numerous German government ministers and politicians from all three coalition parties have openly disagreed with the Chancellor and demanded Taurus deliveries.

If the problem does indeed lie with the United States and is not of domestic origin, it would be impractical for government ministers and politicians to publicly declare their support for Taurus deliveries.

In this case, I would anticipate that government members bear the burden of government policy silently, so as not to strain transatlantic relations, which Germany (and Europe) cannot afford at this time. You may of course have ministers that attempt to influence the US behind closed doors, but I would not anticipate this kind of public inter-governmental debate.

However, if the problem is of a domestic nature, as it seems to be now, we should expect to see exactly what we are witnessing: politicians from different parties openly disagreeing with each other. This not only allows them to score political points but also helps them differentiate themselves from one another.

How long would it take to get a Taurus production line running? There are two aspects to consider:
1) Setting up the physical production line (physical spaces, tools/machines, hiring workers)
2) Establishing the supply chain necessary for production. 1/10

The most recent Taurus cruise missiles were part of South Korea's second batch, ordered in 2018. The final Taurus missile arrived in South Korea in 2020. Since then, Taurus Systems GmbH has not yet dismantled its physical production capacity. 2/10
However, it can be assumed that they would need to rehire and retrain workers. Additionally, some machines and physical spaces may have been repurposed since then. In any case, I assume this represents less of an obstacle. 3/10
