Tail number comes back to an aircraft registered to the Missile Defense Agency, could be a housing for almost any test sensor, including side looking radar.
Black World, better leave it alone! |

View Quote A second G-IIB (N178B, cn 125) was modified by the addition of a large dorsal fairing housing a telescope by Aeromet as the HALO II aircraft for the Missile Defense Agency.[11] HALO-II and IV High Altitude Observatory #2 Gulfstream-IIB HALO-II is an airborne observatory that offers excellent performance, adaptability and endurance for its mission. The capability to fly at very high altitude, above obscuring clouds and atmosphere, provides the HALO-II sensors a clear view of mission targets. The EO/IR sensors are mounted in a pod on top of the fuselage, enabling excellent azimuth field of regard and horizon-to-horizon elevation viewing. HALO-II is modified, maintained and operated by L3 Aeromet. If you have the Aircraft Registration Number, you can find out all kinds of things... |

Looks like a movable segment at the front of the hump, above the foreward most passenger window.
I'm guessing that a camera that looks sideways goes in place of that removable/movable looking panel. |

I'm surprised it's so far forward. Maybe it would cause inlet distortion if they moved it further back?

It's like a jet designer saw a hornbill and said Yep, nature had it right with that one!

Test version of the interdimensional drive Tesla is working on.
Since it creates a wormhole that can't be closed, it will doom us all. |

that there be your taxes hard at work... now back to work, that stuff isn't cheap

We have a civilian Missile Defense Agency?
Do we not have a USAF, US Army and US Navy responsible for various forms of missile defense, and they all fall under DoD? |

View Quote I was surprised to see it was a telescope pod. usually when .gov/.mil aircraft have big bumps or pods like that, they're usually radars, or some combination of radar and JSTARS type comm gear. I'd have figured if it was for missile defense testing it would be for relaying telemetry or interceptor communications etc. That it's actually a telescope/camera related to missile interception is pretty cool. I would guess it's in infra red, where getting up to a max cruise altitude means 99% of the air and moisture that would absorb or scatter the IR is below you. That's what the NASA SOFIA 747 does for infra red astronomy. But there the telescope is much bigger, and not in a "pod", but actually inhabits a turning section of the 747's fuselage near the tail end. https://www.nasa.gov/mission_pages/SOFIA/index.html One of the recent things they were working on was trying to get observations of the next "Plutoid" mini ice-planet that New Horizons was going to get a flyby of after it's visit to Pluto. They were using the SOFIA plane and telescope because they could (try to) line it up exactly with a star, have it blot out the star for a moment, and then see if there was any dimming of the star from an atmosphere before it went behind the planetoid completely. They did a similar mission for Pluto a few years back to help gauge how much atmosphere/haze Pluto had so they could plan New Horizon's photos. |
