SL-AMRAAM

Featured Replies

Checking out the SL-AMRAAM in the DB (Humvee-based AMRAAM SAM) and saw that it has the same range as the AIM-120C7. All the discussions I've seen on this system indicates that it has a much smaller range than the air-launched version and is inferior to Patriot range.

Its true that air launched weapons that are then applied in the surface launched role typically have considerably shorter ranges, for obvious reasons (e.g. that bum rap called gravity, lack of own launching aircraft momentum, etc).

 

I understand that the version used is the AIM-120C7, and lacking precise details about its range in the surface launched context, I've just used the air launched weapon. If you have credible sources showing effective range, I'd be happy to create a dedicated ground launched version for SL-AMRAAM and put it the HCDB.

It's in the DB for HCE already but with the C7's full range. I was going to use it for a scenario but not as it is now.

Yes, I'm well aware its already there. What I'm saying is do you know of more precise (and credible) specs for the SL-AMRAAM ? That's a prerequisite to me changing what's there now.

Well, no, I don't. But I would think a good compromise might be to scale it similarly to NASAMs is to the AIM-120A/B until more data is known.

I'm prepared to work with you, especially if you're building a scenario. (Always encouraged ! ;) )

 

Part of my design philosophy with the HCDB - if you're not already aware - is summarised as follows: Use the most accurate, up to date information available, and wherever possible, the latest accepted Harpoon paper rules data (i.e. Harpoon 4.1/High Tide) will be taken as correct. I try and avoid guesstimating wherever possible, but sometimes an educated guesstimate is all we have.

 

So let's see. NASAMS shows range 12 nm (about one third of the AIM-120A/B's air launched range).

 

SL-AMRAAM (with the AIM-120C5) currently shows range 60 nm. One third would be 20 nm. Does that sound reasonable to you ?

I agree, we want to keep the DB as accurate as possible and in line with what the community knows from open-source material - especially Harpoon canon materials.

 

My point here is that the current version is already flawed so a change to a more reasonable figure.

 

This article: http://www.defense-update.com/products/s/slamraam.htm - states it is essentially equivalent to NASAMS

 

This one: http://www.raytheon.com/technology/stellen...ms01_048569.pdf - from Raytheon, also states NASAMS equivalence. It also states a '30 x increase in battle space over line of sight weapons'. Most low level LOS SAMs have a range in the 2-3nm region. Let's be generous and say 3nm radius. That yields a battle space of pi*r*r of 28.27 sq nm. Apply that to 30 x that and you get 848.1 sq nm or about 16.4 nm radius.

 

The Strategy Page: http://www.strategypage.com/htmw/htada/art...s/20060731.aspx - lists a range of 25km or about 15.6 nm.

 

Somewhere in there lies the answer. However it's not 60 nm! ;>

One more thing - according to Army Technology Raytheon announced an SLAMRAAM-ER (probably based on the AIM-120D) with a range of 40km.

Okay, if we accept that the SL-AMRAAM ER will have a range of 21.6 nm (40 km), and considering the info suggested in the other sources (I've seen those as well), I'm prepared to revise the existing entry to 16 nm. (Until we have better info, at least).

 

Don't be surprised if you find other entries in the HCDB which need adjustment from time to time. If you ever get into maintaining a DB of your own, you'll quickly discover that it is ALWAYS a work in progress. In the meantime, thanks for your suggestions here.

I share your pain, Brad. I'm a long-time Harpoon gamer (paper and computer) and had to extrapolate and modify many a time. Thanks for you hard work!

Whoops! I used the wrong conversion on the Strategy Page figure - 25km = 13.5nm.
