The most interesting option in my opinion comes with the Sikorsky CH 148 helicopter as it could be a common platform for both reuirements although it would be hard for Sikorsky to fulfill the Air Force performance requiremnts.
The article below says that for the CSAR order Eurocopter have been asked as well. This seems to be wrong. The NH 90 and EC 725 were considered too small earlier therefore it is more likely that FI meant Agusta Westland instead, which is offering the AW 101 to the Air Force (see second article).
This will be a very interesting decision as the German Minister of Defence is not very pleased with EADS due to the delays of the NH 90, Tiger and A400M. Therefore it is very likely that Sikorsky will get the Navy deal, as the CH 148 is also been favouvered by the Navy over the NH 90. Sikorsky announced that they are building up a team with German companies such as MTU and Rheinmetall and others.
Boeing is working together with EADS on the new HTH (http://www.airliners.net/aviation-forums/military/read.main/123485/) so the CH 47 does not seem so far fetched as it seemed earlier.
For more information see the two articles below:
Sikorsky is busy at the show assembling its team to bid for Germany's twin requirements for an air force combat search and rescue (CSAR) helicopter and a replacement for the navy's ageing Sea Kings.
Discussions with MTU Aero Engines are well advanced and a deal should be agreed during ILA, while an expected agreement with Rheinmetall is further off, said Sikorsky vice-president sales for Europe, the Middle East, Turkey and Africa, Joseph Gigantelli, at the show yesterday. Ruag and ZF Luftfahrttechnik have already signed up to the team.
Sikorsky aims to persuade Germany of the merits of choosing its S-92-based CH-148 Cyclone as a common platform for the separate air force and navy requirements, despite the fact that some of the former's performance requirements may not be met.
The air force and navy selections are due to be made during the fourth quarter of 2010, leading to contract award in 2011. Boeing and Eurocopter are also in the running for the air force order, while the navy RFP was sent only to Eurocopter and Sikorsky.
AgustaWestland proposes AW101 for Luftwaffe CSAR requirement :
AgustaWestland has pitched its AW101 platform as a means of meeting the German air force's combat search and rescue (CSAR) requirement.
The Luftwaffe requirement encompasses in-flight refuelling capability, enhanced self-protection and all-weather net-centric avionics, including satellite communications. It also seeks the ability to recover a seven-person team with the same number in the rescue-aircraft team.
