What open source info is there on the specifics of each "block?"

While normally I don't like referring to Global Security, I have to say that they seem to have copied the block info from the now - no longer available document from LM. At least I cannot find it anymore. The following is what they had posted:

**The Block 10 Initial Operational Capability configuration, to be fielded this year, will be multirole, with the option of four AMRAAMs being replaced by GBU-32 JDAMs. This provides an analogous deep-strike capability to the F-117A, but is more survivable.

**The Block 20 configuration is the baseline for the Global Strike Task Force (GSTF) fleet, and will include JSF common radar modules, a dedicated high-speed radar processor, and COTS technology CIP processors. The GBU-39/40 Small Diameter Bomb is introduced in the Block 20 aircraft by 2007, together with high resolution SAR radar modes, improved radar ECCM, two way voice and data MIDS/Link-16 capability, improved crew station software, and improved electronic countermeasures.

**The Block 30 configuration, planned for 2008-2011, extends the growth seen in the Block 20. Side-looking radar arrays provide a significant ISR capability in the aircraft along with enhancements to provide full Wild Weasel air defence suppression and time-critical target engagement capabilities. A Satcom terminal will provide continuous network connectivity during deep-strike profiles.

**The post-2011 Block 40 aircraft is intended to be the definitive Global Strike configuration, with incremental enhancements to Block 30 additions providing full sensor networking, range enhancements, integrated ISR capabilities, and a Helmet Mounted Display similar to the JSF.

**Longer term planning for a Block 50 envisages an Electronic Attack variant, replacing the lost EF-111A Raven. A stealthy stores pod for JDAM and SDB is under development to enable carriage on external pylons. As a strike aircraft the F/A-22A will have similar internal payloads to the JSF, but will be vastly more survivable due to better stealth.

LAVI...while I'm glad to help, please keep in mind this info appears to be the same that was available from LM...at least to me, however, it may not all be correct...Check

Interesting reading I'm doing from an unclassified source....copy and pasted....JJ, I'll either send you the PDF files or tell you where you can find them...Check

F-22A Modifications: Spiral 3A modernizes F-22A aircraft with Enhanced Central Integrated Processor (ECIP) cards, a new Map Inter-Face (MIF) board for the 4th generation APG-77V1 radar, a modification to the GPS Inertial
Navigation System (GINS), and a Tactical Data Transfer System (TDTS). These hardware modifications enable the F-22 to retarget Joint Direct Attack Munitions (JDAM), carry and deliver the Small Diameter
Bomb (SDB) on preplanned missions using the Joint Mission Planning System (JMPS), to use a Synthetic Aperture Radar (SAR) Air-to-Ground radar mode to permit attack of emerging targets using SDBs, and
to save SAR imagery onto the the TDTS for post-mission analysis.

Check-

While obviously not your fault, I agree that the data in your first post is not correct, in MANY areas. That's probably why LM pulled it in the first place.

Most of that Block/incremental improvements progression is now completely different. That original LM document is wildly out of date, probably originating to the 2002-3 timeframe.

The second post looks better....many of the (really great) upgrades listed in the first document have, unfortunately, fallen off the track for lack of funding.

Yes, it's unclassified. At least now it is...

The Weapon System Evaluation Program (WSEP) is essential for F-22 training and test. The capability provides a flight termination signal (FTS) and re-radiation within the weapons bays. The flight termination signal is used to terminate a missile in flight if necessary. The re-rad capability allows us to re-radiate targeting data into the weapons bay and to the missile, as well as radiate the FTS. This money will be used to procure the necessary group A wiring and the WSEP boxes themselves. The WSEP boxes will be stored at various AFB, and is designed to be interchangeable among aircraft.

Yeah, thats what I thought. At least you know what I was referring to from LM and now I know I wasn't crazy when I couldn't find it! Thanks! Thumb

Many thanks for your worthy input, checksixx and BlueFour! Some of these details are absolute new for me. Especially in case of our already launched F-22 Aircraft Database, I still want some official LM F-22A aircraft type designations (including verified block numbers). Next week, I will finally contact Joe Quimby, F-22 Communications Manager, Lockheed Martin Aeronautics, for further first-hand support. To checksixx: I also had some bad experiencies with www.globalsecurity.org, but in some cases they have archived some hot and very helpful documents. Secured you the original and no longer available LM document related to Block numbers? If yes, please e-mail me the stuff. That would be great!

Everyone,

Thanks for updates and if you get more specifics please let me know. If you need to PM anything that would be terrific as well. Otherwise I will just check the database on a more regular basis.

In their November 2006 online issue, "Aviation News" (Britains longest established monthly aviation journal) stated:

Quote:
In September 1992 a ground-attack mission was added to make the aircraft more Congress-friendly, and it became the F/A-22. At the unveiling of the first EMD aircraft in April 1997 the F/A-22 was formally named ‘Raptor’. It had its maiden flight on September 7, 1997. The F/A-22 designation lasted only until late 2005, when it was decided that ‘Attack’ was the kind of language that only Navy people use. The EMD aircraft were followed by two production-representative test vehicles (99-4010 and –4011) and six PRTV-II aircraft (00-4012 to –4017). Next came a series of low-rate initial production (LRIP) orders: ten aircraft in Lot One (01-4018 to –4027), 13 in Lot Two (02-4028 to –4040), 21 in Lot Three (03-4041 to –4061), 22 in Lot Four (04-4062 to –4083), 24 in Lot Five (05-4084 to –4107) and 24 in Lot Six (06-4108 to –4131).
The first production delivery (serial 01-4018) was to Tyndall AFB, Fla, on September 26, 2003. Following the current Block 10 F-22s, Lot Five aircraft are being built to Block 20 standard, which will have full air-to-air capability and clearance for the supersonic release of JDAM. Lot Six of Block 30 aircraft will have an improved version of the Northrop Grumman APG-77 radar, two-way Link 16 data-link, and clearance for the GBU-39 Small Diameter Bomb. Having earlier planned to ask for funds for 29 F-22s in FY2007, the number was then zeroed by the USAF, in the expectation that procurement could be completed more economically under a later multi-year deal. However, in August 2006 the Senate added $1.4bn funding for 20 F-22s in the FY2007 budget.


For the full article see their feature <a href="http://www.aviation-news.co.uk/Lockheed's%20dynamic%20duo.html">"Lockheed's Dynamic Duo –
Today’s technologies for yesterday’s wars?"</a>

Excuse me, I knew that´s no first-hand info, but nevertheless interesting!

In the future, I will further update our F-22 Aircraft Database, first established by Jon some weeks ago (Many thanks to Jon for his basic work!). In a first step, I will add the significant Lot numbers to each aircraft, and also some more dates like "final assembly complete" = roll out after final assembly and also "ferry flight" dates (related to the transfer from Lockheed Martin´s Marietta, Georgia, plant to the USAF customer unit). And as I already posted, next week, I will finally contact Joe Quimby, F-22 Communications Manager, Lockheed Martin Aeronautics, for further first-hand support.
