The dispenser you are asking about... the triangle thingy... was not a flare dispenser; it was a CBU (Cluster Bomb Unit). Those tubes were filled with bomblets (BLUs... prounounced "bluies"). The dispenser was a SUU-14 (and variants) and the CBU was numbered according to what bomblets were in it. (I.E. CBU-14A) One version we flew had bomblets shaped like a baseball with giant seams to act as fins and cause it to spin... the other had bomblets that looked kinda like a giant badminton shuttlecock. Here's a link to more than you probably wanted to know:
http://www.designation-systems.net/usmi ... tml#_SUU14The tubes were a bright, shiny metal with a gold tinge... so we always painted the bottoms. These were used as anti-personnel (or very light armor) weapons. So we did not load them much for use against "The Trail". We did use them more when we were "fragged" to go up north into Barrel Roll (Barrel Roll was in the northern portion of Laos around the "Plane of Jars") in support of Royal Laotian Troops. We did not fly to Barrel Roll very often... only when the Royal Laotions were in dire straights or during rainy season when "The Trail" was weathered-in.
Of note... the A-1s used thousands of CBU-14s for SARs (Search And Rescues). It was part of the standard "SAR alert birds" (Sandys) load. When a SAR got "hot" we would load them by hand since they were light enough. (A-1s only... the A-26s were not Sandys when I was there.) We never painted the bottoms since the SARs were only daytime missions. (I only participated "full force" with the A-1s in only one SAR after the Nimrods were dis-banded... the Boxer-22 SAR, 5-7 Dec '69.
The dispenser (SUU-14) was designed to be brought back and re-used. In my memory, I don't think any of them ever came back. Perhaps one of our pilot types can tell us what they "bombed" with them.(Sorta like the "Beer-Bottle Bomber", Joe Kittinger I suspect). During and after the war... and still ongoing, there has been a huge scrap metal business in Laos. There were millions of bluies dropped in Laos with lots of UXOs as a result. Every year they find more UXOs... some the hard way.
One final note... it's interesting that Randy and I are kinda book-ends. He started the Nimrod's time at NKP with "Big Eagle"... near the end of my year, I closed it down (*sad face*). The tactics and munitions really did change from his time to mine. All of the missions during his time carried their own flares... none during my time carried them. Our missions all used mostly C-123 "Candlesticks" and some C-130 "Blind Bats" for "lighting up" the world.
