Official renderOsprey is the largest of Blackwing Space's three satellite platforms, a 6U XL with four battery packs.
blackwing-osprey Osprey is the largest of the three satellite platforms that Blackwing Space sells. It is a 6U XL, 366 by 226 by 100 millimetres, rated at 10 to 60 watts of average power over an orbit. Like its smaller siblings it is sold online, and Blackwing says its rails suit late additions to shared launches.
The frame is 6061 aluminium with a hard anodised finish. Four Puffin battery packs store 300 watt-hours between them. Whether the frame is qualified for SpaceX rideshare launches is still marked 'to be confirmed' on Blackwing's chassis page.
The largest of the three platforms: a 6U XL bus with an 8 kg payload and 60 W of orbit-average power. It suits payloads that need more mass, volume and power than a 3U can offer, with the same online pricing and late-manifest rail format.
Blank side panels are optional, and fasteners come with guided assembly instructions. The frame carries built-in mounting and electrical connections for solar arrays, a de-orbiting device, antennas and radiators, and optional mounts for deployment switches.
One Rook board, the type Blackwing uses across its range, runs the platform. It is a four-layer FR-4 circuit board that holds the flight computer and the power electronics. A charge controller, fed by solar panels or a USB-C cable, charges four Puffin Packs of lithium-ion 18650 cells.
Extras include an S-band radio, an Iridium backup link, precision pointing control and two electric propulsion options, standard and advanced. A passive drag sail can be added as a deorbit device for the FCC's five-year lifetime rule. Solar panels can be body-mounted or carried on deployable wings.

A draft Blackwing specification names a carbon composite shell as an alternative to the hard anodised finish.
Blackwing says Osprey complies with the CubeSat Design Specification and the PC/104 board format. Four dispensers are named as compatible, from SEOPS, Maverick Space Systems, Exolaunch and Spacemind, and the same four fit Sparrow and Kestrel. The Rook computer grew out of the open-source PyCubed design. Blackwing's pages mention no Osprey flight.
Compatible deployer: 1U to 12U, tab and rail, up to 96U per port, flown on SpaceX Falcon 9 rideshare
Compatible deployer: ruggedized 6U (or 2x3U) dispenser with NASA Ames NLAS heritage

Blackwing publishes no datasheet, developer page or interface guide for Osprey. Its pages give two different payload masses, one marked 'to be confirmed', and two different weights for the frame. Fastener and side-panel materials, the type of anodising and the suppliers of radios, solar panels and thrusters aren't given.

No Osprey developer page, payload interface guide, drawings or STEP file are published (Blackwing says Kestrel developer tools are in development; the Sparrow guide is the only published interface document). The pricing page says all platforms share the same payload interfaces, but the Sparrow payload module drawings are Sparrow-specific and are not applied here. No anodize standard, fastener material, side-panel material, or connector part number for this platform is stated. Chassis pages say 'Aluminum 6061 T6 or T651' without saying which. The Osprey chassis page marks payload mass and frame qualification as TBC. More detail: Osprey has no published developer page, interface guide or drawings (listed as coming soon). No bill of materials: fastener count and material, side-panel material, anodize type, solar panel and radio suppliers, ADCS and electric-propulsion suppliers, thermal coatings and adhesives are not stated. The chassis page marks payload mass (6 kg) and frame qualification as TBC while the pricing page gives 8 kg. The draft Specifications page quotes 0.80 kg for a 6U structure against 1.2 kg on the chassis page. No Osprey has flown according to the pages read.
