The X-ray spectrum of the broad line radio galaxy 3C 445 is strikinglyreminiscent of that of radio-quiet Seyfert 1s (e.g., NGC 5548) when they areobscured by massive, fast winds located within the boundary of the broad lineregion. We propose a joint XMM-Newton (110 ks) and HST program that willdetermine the physical conditions of all the phases (namely Fe-K and UV/softX-ray absorption) of the nuclear outflow in this source. This will be the firstcase ever confirmed of an obscuring wind in a radio-loud object, with farreaching consequences for our understanding of the role that obscurationepisodes play during the AGN lifetime.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
