I am searching for the definition of \maketitle in the article class.
I searched on CTAN but there is a lot of files. I don’t know in which one I can find this definition.

If you used scrartcl instead of article, the command \subtitle would immediately work as expected. scrartcl belongs to the KOMA-Script classes which are extended replacements of the LaTeX standard classes. I strongly recommend KOMA-Script. For reasons have a look at:
Your document is considerably large. An article-like class may be ok (scrartcl), but if you need a chapter-like sectioning you could consider to use report (or scrreprt, which is a KOMA class).

If there are only one author and one class (i.e., without using \and), some like this could be enough:
\documentclass[11pt]{article}
\makeatletter
\def\class#1{\gdef\@class{#1}}
\def\@class{\@latex@warning@no@line{Hey you, no \noexpand\class given}}
\def\@maketitle{%
\newpage \null \vskip 2em%
\begin{flushright}%
\let\footnote\thanks
\vskip 1.5em%
{\large \lineskip .5em%
\begin{tabular}[t]{r@{}}%
\@author
\end{tabular}\par
\begin{tabular}[t]{r@{}}%
{\sffamily \@class}
\end{tabular}\par
\par}%
\vskip .5em%
{\small\@date}\par\bigskip%
{\LARGE\scshape \@title \par\bigskip\hrule}%
\end{flushright}%
\par \vskip 1.5em}
\makeatother
\title{Some long Wonderfull Title}
\class{UFO affairs\thanks{Area 51}}
\author{Clever Reporter\thanks{No dot disturb.}}
\date{\today}
\begin{document}
\maketitle
\end{document}
If you can have several authors and classes, then left the tabular as environment as originally defined (with one ccolumn type) and simply use \author{author\\class \and author\\class \and ...}
