Talk:Tactical High Energy Laser

message: The "oh this might not work" section seem to be much smaller than the "oh, it's great" section.  Especially in light of the SCADS of evidence that this (and similar systems) won't work due to the desires of politicians being second to the simple facts of physics.  I know, my POV is showing.  I'll back it up with some citations soon. - brenneman(t)(c) 06:27, 9 November 2005 (UTC)
thread_title: NPOV

message: ...just like any other encyclopedia, not to be a political platform for debate about the topic. The article as written largely accomplishes that purpose. It does need some factual updates, as the MTHEL system has been recently delayed due to reduced Israeli financial participation.

replies: text: After further review I agree there was some non-encyclopedic stuff of a press release nature. Removed or rephrased that to make it more factual. The purpose of an encyclopedia is NOT to present pro/con options about items, but convey factual descriptions. Joema 17:02, 2 January 2006 (UTC)
thread_title:  Main Purpose of Article is Convey Descriptive Information About Stated Topic 

message: - it is written here, that the "Red Color" (formerly, Red Dawn (alert)) alert makes use of the programm's radar, located near Nahal Oz, though the laser itself isn't there...

thread_title: Radar

message: The first line of this article reads "The cooperative Tactical High Energy Laser (THEL) Demonstrator ACTD was designed and built by the United States and Israeli governments on July 18, 1996." Unless the two governments actually designed and built the whole thing in a single day, I'm not sure what this refers to. Is it the start of the contract? The first test firing? The original expected delivery date? The day the initial proposal was submitted? 134.117.219.243 21:31, 13 November 2007 (UTC)
replies: text: Thanks for catching that. The wording was caused by a botched edit by an anon contributor, which was never corrected. I looked up and restored the original wording. Joema 04:04, 14 November 2007 (UTC)
thread_title: Dates

message: I've believe ablative refractive (ceramic) coatings are the sort of thing any feasible upgraded Qassam would have; instead of a mirrored finished. Where as ablatives force the laser to have a increased dwell-on-target time, mirrors are useless unless they can reflect a substantial portion of the incoming energy (which in this case is infrared vs visible light). Under the manufacturing conditions the rockets are made under, it would be easier and probably more effective to procure and transport, say Titanium Dioxide vs polishing the rocket casing. ~~No Account Yet (sorry)  —Preceding unsigned comment added by 74.127.199.248 (talk) 23:50, 10 May 2008 (UTC)
thread_title: Refractive vs. Reflective

message: Assuming that we coat rocket head with quartz glass(which is transparent to all possible laser radiation) or other high temperature and low light absorption ceramic, it is quite possible that it will require unrealistic amount of energy to heat that rocket shield enough to melt . 
Only thing what laser can be used is to blind rocket heat seeking device. 
Even moderately primitive rocket can be made invulnerable to such weapon or it can even use its radiation as guide.
Furthermore it is theoretically possible(and partially tested) to use laser energy as additional energy source to drive rocket.
so this laser system can be used to power and steer own rockets which will severely reduce amount of required fuel increase distance or payload or reduce rocket cost.  —Preceding unsigned comment added by 88.118.69.71 (talk) 22:16, 1 September 2010 (UTC)
thread_title:  Any calculatuions? 

message: "# In a similar vein to the above, a rotating missile will halve the effective area over which the radiation is incident, yet another countermeasure technique or method. This occurs as it is assumed that there would only be one direction from which the THEL radiation would be incident – but this technique has a countermeasure effect even when there are multiple THEL laser radiation sources pointed at the same projectile (assuming that there is some outer boundary area of the missile upon which no laser radiation is incident)."
That is the silliest thing I've ever read on lasers.  Artillery shells spin due to rifling of the barrel, many rockets spin due to poor construction or stability.  The laser arrives at a billionth of a second, a dancer at pirouette in front of a gun but it won't do any good.  This argument is a decades old one against SDI, wong then and wrong now.Lyta79 (talk) 19:54, 31 October 2009 (UTC)
thread_title: Rotation

message: It seems to say "this laser is cheap, almost 100% accurate, mobile, and just what is needed to defend against the rockets etc coming from (for example) Gaza, but it has been discontinued in favour of nothing".  Why was it stopped, and what are current plans for the future?
Also, the second paragraph of 'demonstrator' is talking in future tense about 1998! Sparrer (talk) 18:12, 10 December 2008 (UTC)

thread_title:  Copyright problem removed 

message: The "Heat Resistant Coating Layers" section discussing "fall away layers" is entirely inaccurate when referencing the Space Shuttle. The Space Shuttle thermal protection system is not designed to fall off the Shuttle. There were early problems with the adhesive holding the tiles to the aluminum structure of the Orbiter, but they were NEVER designed to do so, and in fact the loss of ceramic thermal tiles at critical locations is a potential source of catastrophic loss of the vehicle. This entire idea should be removed from the article.

thread_title:  Space Shuttle reference? 

message: I'm not sure about this, but the policy of wikipedia is not to describe at length how to do something. Basically, this is usually intended to stop people writing tutorials. But I think it may be relevant in this case, as there is an extensive write up of how to make counter-measures for this weapons system. I'm sure someone found a great source listing potential arguments for counter measures, but describing them in such detail, especially in comparison to the minimal detail on the actual laser system seems unbalanced at best, and a breach of not-how-to at worst. However maybe thats just my interpretation.--Senor Freebie (talk) 23:07, 15 February 2010 (UTC)
thread_title:  WP not howto? 

message: Over 72% of the entire article consisted of unverified claims just having to do with countermeasure proposals.  The section was tagged well over a year ago for OR with nothing done and someone actually thought fit to expand upon it with a new sub-section with more unsourced content.  Unbalanced, unsourced, and unencylopedic.  Readers gain no deeper understanding about THEL by reading theoretical, poorly written proposals on how to counter it.  Removed/Rewrote unnecessary elaborations, subsection, and section on problems with countermeasures.  If someone would like to source 'em and expand from there knock yourself out.  Just try to keep it balanced with the rest of the article.    \sim  ℗ papajohnin   (talk)(?) </b>  —Preceding undated comment added 08:16, 21 October 2010 (UTC)
