Considering they entered service at that time, the age of their combat suites makes sense.

Unless you wish the designers to travel into the future, get technology, and then travel back in time to install it.

Argument is irrelevant, combat suite on the Aradu is 35 years old.

What is the radar cross section of the guns turret? I dont think you understand what stealth is

The company completely ripped off the South-African government.

S.A government paid too much for a substandard system. Anyway, trust patches689 to deny the obvious.



SA Navy frigates combt suites are obsolete!!

1. Where does it say in your source that it is obsolete?
2. Where does it say in your source that it does not meet requriements?
3. Why would the french navy install obsolete technology on their flagship and latest Frigates?
4. Why would the Saudi's install obsolete technology on their latest and most advanced frigate?

Stop wasting out time with pointless emotionally driven arguments.

Combat suite of Aradu was changed in 2001 refit. Same level with Valour frigate

Same combat suite is in operation in the French navy with their newest firgates, their flagship and the Saudi's newest warship.

So the french ripped themselves off as well?

240. Furthermore, a number of the evaluation team's criticisms of the Detexis system identified aspects where the Detexis system did not comply with the baseline requirements specified in the URS (in particular, Points 1, 4, 7, 8, 10, 13 and 15).

241. The IMS was in fact (as the evaluation team found) a superior product and the Detexis system was in fact deficient and failed to comply with the URS

agaugust:


Nope, that combat suite is on 20 year old French warships that existed almost a decade before Valour frigates, according to your own source.

FREMM frigate and Horizon are the new frontline warships of France.

Only South Africa got ripped off as usual.....plus a 38 year old main gun on your new warship, $300 million frigate
.

Henry120:


"Are we discussing France or South-Africa?".


Your combat suite did not even comply with Amscor URS.


Obsolete boat for an obsolete Navy!

241.2 furthermore, the combat suite based on Detexis system is essentially a hard-wired point-to-point solution rather than being bus-based and its potential for growth and upgrading is thus severely curtailed; this being directly contrary to the SAN's own formally stated RFO requirement;
[DT1-0321.pdf]


241.3 the Detexis system does not provide synchronised clocks for the time-stamping of data;
241.4 the transfer capability of the Detexis system is only 165 bytes in 6,5 milliseconds, which falls far short of the capability required by the URS (4 000 bytes in not more than 5 milliseconds);


241.5 the Detexis system's node-to-node synchronisation accuracy is at best only of the order of 10 milliseconds (10 000 microseconds), contrary to the 500 microseconds in a worst-case scenario as specified in the URS - a factor of 20 times worse. In fact, the end-to-end synchronisation accuracy of the combat suite based on the Detexis system will be considerably worse than 10 milliseconds due to its hard-wired component. This accuracy is critical to the combat suite's air defence function;[/b]

Valour frigate refit ? Did you change the whole combat suite ?

Show us proof !

Sources say you changed old engine, is diesel engine your combat suite ? Olodo Rabata

Do you know what URS means and what requirments were stipulated?

I found the source you are using (despite the fact that you wouldent post it because you knew we would see that you were posting sections out of context!)

I know, and I know you have been posting trash again.

Ok

You have shown that there are better systems - which cost more money

You have shown that the URS were changed while the project developed.

Now, show:

1. How does this relate to your allegation that it is obsolete?

2. How does this make the Valour Class inferior to anything in your arsenal?

As usual, you displace stunning cognitive dissonance

A boat that doesn't meet the basic requirements of the buyer is obsolete.

SHOW US PROOF OF ARADU COMBAT SUITE REFIT!!

241.6 the real-time performance of the Detexis system is deficient due to its employing the Transmission Control Protocol/ Internet Protocol ("TCP/IP" which has inherent deficiencies in this regard, specifically its Time-Wait state machine and primitive message priority scheme. According to the Internet standard RFC 793 a connection can stay in a Time-Wait state for a maximum of four minutes known as a MSL (maximum segment lifetime); this is highly deficient and unacceptable for a real-time system such as the combat suite;

agaugust:


You and I have argued this last year and I proved it all, I updated it on wikipedia and showed my sources to EVERYBODY on this thread last year, Harpoon databases and Spanish navy ships website. I see no need for a repeat, "In 2001, another refit (with American assistance) was undertaken, and the ship returned to operation. The obsolete AWS 5 radar and PHS sonar were replaced with a Signaal STIR (I/J/K) 60 nm/120 km fire control (range, bearing, altitude), DA-08 90 nm/180 km air (search, track) as well as an Atlas EA80 20 nm/40 km passive anti-submarine sonar (bearing, class), in addition to these, all other systems including weapons were cleaned, overhauled and put in good working order."

Now you show us proof of new combat suite in Valour frigate, that you have removed the 20 year old navionics...show proof !

241.7 the Detexis system attempts to achieve system reliability by means of a combination of dual-redundant, dual-homed Fast Ethernet switches, duplicated Network Interface Cards ("NICs" and software-implemented data packet duplication and selection logic, but reliability is compromised by the following :

241.7.1 the use of duplicated NICs is undesirable since hardware is doubled and each NIC requires the processing resources of its host, which is limited;

241.7.2 data packet duplication and selection is a potentially dangerous redundancy mechanism in mission-critical systems, since it violates the atomic commitment principle, namely that data transactions should either complete successfully ("commit" or fail completely ("abort", with no partial state. This is violated by the transmission of duplicate data packets.

242. The Detexis system also failed to comply with the requirements of the NSR quoted above in the following respects :

242.1 in the Detexis system the combat suite as a whole is not "based on" an architecture using a databus. Only the CMS component of the combat suite utilises a databus. The CMS in turn connects to the rest of the combat suite by multiple point-to-point (or hard-wired) links; and

242.2 the databus in the Detexis system is thus not a "multirole" databus, since it provides functionality to the CMS only and cannot provide clock synchronisation nor timestamping services nor bulk data transfer services to the combat suite, those being inter alia the functionalities of the databus specified by the URS (Para. 7.1.1 thereof);


242.3 the combat suite architecture based on the Detexis system is essentially a point-to-point system and such a system cannot be described as
